At least it can down at Hunt and Darton, the cafe opened for the entire month of August by live artist double act, Jenny Hunt and Holly Darton.
Last year, the St Martin's College of Art graduates ran the place in St Mary's Street with a sense of style and wit that made it the ultimate drop-in centre.
Inside the cafe's vintage environment, our hostesses and occasional guest waiting staff serve basic but carefully prepared meals, snacks and drinks with meticulous customer care. Some days are be themed, with customers being asked to serve each other, or asked to choose a record to play on an old Dansette.
With each financial transaction carefully marked on the wall in chalk alongside details of the outlay for supplies, at the end of the week, the total profit is also be marked up. In the evening spontaneous happenings occur, and the entire month is one non-stop performance for Hunt and Darton.
"It has evolved a lot since last year," says Darton. "We have a lot of new things happening, like a health and safety day, and have a point of each day, such as austerity."
Another addition to the Hunt and Darton Cafe programme is a set meal for a mere £5. These will be served on a silver trolley, after which "things happen," as Hunt puts it.
"We've always had alternative careers in catering to fund our art," Hunt explains. Darton adds: "It developed organically. We were interested in the relationship between food and art, and also in trying to close the gap between audience and performer."
Hunt continues: "Every time we work together we understand it so much more, so now it is becoming much more immersive, and much more about embracing the customer experience."
The guest artists who will perform in the cafe in the evenings include refugees from the Glasgow-based Buzzcut live art festival, as well as Arches and Forest Fringe regular, Richard DeDominici.
What of the casual customer who goes into the cafe and just wants a cuppa and a cake without any side order of live art?
"The majority are incredibly positive and do join in," according to Hunt. "There are people who just want a cup of tea, and it is our job to try and negotiate that. We are not aggressive about it, but we are assertive."
While in St Mary's Street, Hunt and Darton will also be presenting a show entitled Boredom, looking at the highs and lows of tedium.
"It is the opposite to what we have been doing with the cafe," says Darton. "We are performing it in a guerilla style, and it is taking us back on to a stage."
While they plan not to be working as many hours as last year, Hunt and Darton will need to be 'on' for the entire day, tea breaks permitting. "We do find ourselves doing a lot," Darton admits, "We both really enjoy durational performances, and this year I think we are doing duration for duration's sake."
Hunt puts it much more straighforwardly: "We are also workaholics."
Hunt and Darton Cafe is at 17-21 St Mary's Street until August 25
