I worked at McDonald's and it wasn't great but that was because the managers were rude and didn't care enough to train me at all. In general I'd say fast food is all pretty much the same, easy to pick up on, not usually the best customers to deal with, but you usually get free food. Just gotta try and find a place where the managers are nice. Try to pick a place that's newer built rather than one that's been around a long time.
