One of the places near us used to do any pizza for collection for CHF 10. They recently increased it to CHF 12. Delivery I think they are more like 18+, which puts them in competition with a better place.
I never used to tip takeaway delivery on the rare occasions we ordered it. However, we now live up 6 flights of stairs, so I now give them at least a couple of CHF pour encourager les autres to bring it up rather than have me run down.
Running up 6 flights of stairs is excellent exercise and a great way to get a free sprint interval (30s at maximum heartrate). I do it every day while carrying a bike.
So, 11 years on, have we definitively decided on this?
Restaurant: Round up to nearest 10, unless meal exceptional.
Delivery Guy/Gal: Can do it in app afterwards if they were good, but in general not needed.
Postperson: No - maybe a nice tip at Xmas if you like them.
Heavy Goods Delivery: If they do a good job bringing your sofa in and getting rid of the other one, give them 20 so they can get a beer or two after their shift.
Removals People: They've been humping your shyte around all day, give them a little bonus if they're not complete a-holes.
People giving great advice on EF: I'll provide my twint shortly...
I'd never go there because the corner cutting to get to 10 CHF should produce subpar pizzas. However, I cannot claim I didn't know such poverty existed
