They sell things that come in cups, or with napkins. Lots of people cycle/run/walk here instead of driving, seems pretty stupid.
Taking away the bins doesn’t mean you don’t produce rubbish…
Edit: I think there is still a bin IN the cafe, but most people eat/drink outside. Lots of people asking staff where the bins are. Still hypocritical I think though? (And still mildly infuriating to remove well used bins!)
Idk, it looks like it works (or maybe people are just getting better at not littering and it correlates), but this is one of those things that can be measured so I’d trust department of conservation research over my own anecdotal evidence.
