For france: contactless on phone should be ok with widely used card providers (VISA)

Beware, since covid, use of cash has dramatically fallen, last month a restaurant struggled to give me 2€ change, they didn't have 2€ in cash ! Paying in cash with the right amount should never be a problem though.

France is not America, thank you very much. I have never seen people leave tips here.
