Just learned that a friend of mine always tips 10% on takeout. Ive never tipped on takeout unless they offered me a water/soda while I waited or something.
US biased, but I’m a little curious about other countries as well.
Canada here. For the very rare delivery order I make, I'll do 10%.
For takeout orders, 0, except from my favourite shawarma place because I like them and want them to stay around. They get 10%. Their prices are very reasonable to begin with, so much that I've thought they could charge more.
