There he had to walk past a clutch of jubilant Perth players, thrilled by their surprise success, and push his way though the main doors to reach the Inverness Caledonian Thistle bus. En route, he was halted by a couple of local fans asking for a picture. Butcher courteously obliged before clambering aboard.
The attention was probably unwelcome, given his side had just been administered a fearful hiding, but the sequence of events was instructive. It demonstrated just how far Inverness have come in the past couple of seasons that, not only were those associated with St Johnstone ecstatic at beating them, but that the home supporters were clamouring to record a meeting with the manager.
In short, the Highlanders have become a scalp for every other club in the country. Opponents will tackle harder, run faster and jump higher, while crowds will bray more vociferously and cheer with greater gusto. Winning matches becomes a little more difficult. "When you're sitting high in the league and everyone's talking about you, it can be tough," acknowledged Richie Foran, the Inverness captain. "I think that Aberdeen showed that the way they celebrated after beating us 1-0 at home a couple of weeks ago."
Apart from that game at Pittodrie, Butcher's side were unbeaten going into Saturday's encounter and few would have envisaged a capitulation as spectacular as the one that ensured they slipped from the summit of the SPFL Premiership.
To suggest that Inverness offered nothing would be generous - "there are no positives," the manager said - but some consolation can be derived from the knowledge that they surely will not be as abject again. Not for a long time, at least.
Foran explained that the players and coaching staff would hold a routine debrief tomorrow, after which the game will be forgotten, with attention focused instead on the meeting against Partick Thistle at the Caledonian Stadium on Sunday week. By then, Inverness could find themselves six points adrift of Celtic at the top of the division but there is no danger of any angst afflicting the squad; quite the contrary, in fact. "Look, it's been a wonderful season so far and we've only lost two games, both away from home against really good sides, so it's not all doom and gloom," said Foran. "The main thing is we bounce back and we always bounce back at Inverness."
By then, they may also be able to field the XI who started the opening eight games. Injuries necessitated two changes to Butcher's preferred side for their ninth fixture of the campaign on Saturday and, while neither Liam Polworth nor Danny Devine played particularly poorly, the alterations did appear to affect the team adversely. "The lads who came in are good enough but we've had a settled side and that definitely helps," admitted Foran. "Everyone knows one another's games inside out and is sharp but it's hard for the two lads to come in and get that rhythm. Saying that, young Polworth was actually one of our better players so we can't really blame that."
More pertinent to the pummelling might be the manner in which St Johnstone played. Despite having failed to win any of their previous five league matches, Tommy Wright's team were breathtakingly good at times, with their short, sharp interchanges in the final third befuddling the visitors to such an extent that they conceded the same number of goals in one game as they had in their previous nine in all competitions.
Particularly prominent was Stevie May. Observers of the 20-year-old have come to recognise his strength and opportunism but it was another aspect of his game that caught the eye on Saturday, the striker taking advantage of being deployed up front alongside Steven MacLean to drop off and embroider St Johnstone's play.
May was involved in all four goals, scoring one and providing the final passes that cleaved open the Inverness defence for the others, amid a performance that moved MacLean to lavish praise. "Is there a Scottish striker who has scored more than Stevie May this season?" asked the forward, who himself scored twice in a quietly splendid display. "That speaks for itself. But he's not just been scoring goals; his link-up play and team ethic are brilliant, too. He needs to keep going and see where it takes him, but he is keen to learn and takes it all in - that's a good quality to have."
