When I go to the bakery, which is very close to our flat, I usually get bread, milk and something else (nibbles, pastries, an ice cream, a croissant — or what have you). I am regularly given at least two plastic bags: one for the refrigerated items and one for the loaf. Sometimes I am given three bags: one for each item. They love handing out plastic bags.
I have found out this is not just the bakeries within range, in fact I get so exasperated with their need to hand out as many plastic bags as possible, I once asked one of the employees in the nearby one (we have made friends with some of them). She explained to me they are trained to give out as many plastic bags as possible so that they do not overload and rip open, causing inconvenience to the customers.
Now, because I only live round the corner, and because I always put my bread in a paper bag anyway, so that it keeps better and longer, I usually have to tell them I don’t need a plastic bag, or at least not more than one: I can always use a spare hand for the loaf. Whenever I do this, I sometimes get disdainful looks from the bakery employees, sometimes a smirk, sometimes I get a flash of astonishment, sometimes true grudge: I once went just for bread and had my loaf slammed on the till because I whispered ‘I don’t need a bag, thank you’. Thankfully, they usually just ask ‘what, no bag?’
