OK I can't resist posting this. I've just bought a bacon sarnie from the neat Turkish cafe / deli / lunch shop on the way into the office. No surprise there. The latex gloves on the hands of the two girls behind the counter are a novelty, though - and completely pointless. I didn't ask, but here's how my reasoning goes.
Money is dirty; it's covered with bacteria and viruses. You shouldn't handle money and unwrapped food without washing your hands in between. Or, like many cafes, have different people handling the cash than those handling the food. The girls at the local deli used to do both, with bare hands until last week. I presume someone got a dicky tummy and complained to the Environmental Health, who made a visit and advised that they should wear latex gloves when handling food as an efficient alternative to incessant hand washing.
They should also have explained that they should take them off when handling the cash.
