Not a bad place but they evade taxes in a annoying way.
At the checkout he tells me that the poss doesn't work, I don't have cash and I can't pay it: the poss then (simply turning it on) resurrects. He then tells me that I'm lucky and goes into a lecture on the importance of leaving the house with cash. He repeats the same game with the next people and whoever gives him the cash doesn't receive the receipt.
I understand the difficulties of working in catering and of being resourceful, but if you see that the customer is not cooperating, be smart and don't insist.
