Saw a cracking one at Asda the other day.
The pizza counter lady nipped off the counter to wipe up a squashed grape on the floor with some paper towels, then correctly soaped up her hands, and washed them in the sink. All good so far.
She then proceeded to dry them on her visibly dirty apron, before making my pizza.
Logic?
(I don't really care, I don't think any contamination would survive 15 mins in the oven)
