McDonald's can be cheap-ist. The trick is to stay away from their headline burgers and ask for the simple hamburgers/cheeseburgers instead, which are massively cheaper. For instance, here a hamburger is £1.19, cheeseburger £1.39, medium fries £1.59. Cheap. But of course they focus your attention to fancier burgers which cost £5 to £7.

Feels a bit like casual vilification of migrants.

“Lowly paid” migrants have a high motivation to get the job done properly. They need the money and are grateful for the job that some non-migrants would never consider. If the restaurant is dirty then management is probably to blame.

Management in such situations has tyrannical power. They probably just haven’t prioritised cleanliness in the restaurants you seem to describe.

lucky you. In London, kebabs are routinely >£8 (I've seen >£10), and they are almost invariably terrible. My biggest gripe being that the bread (when it's actually a doner rather than a wrap) is a soft soggy waste of flour. For some reason they also insist on assembling the doner by putting bread at the bottom of a styrofoam box then piling up "fillings" on top of it, making it impossible to eat on the go.

It's not like it's hard? They already have the right ingredients, I'm not even picky about quality, just get half-decent bread and you're good to go!
