yes thats what i do all the time
unless they sell cibai price for mineral water like el cerdo then i probably order some other drinks. or drink from my own bottle if i bring one (just tell them it's medicated water if need to).

if you sell harga yahudi and give me fuck face when i din order then i fuck off lo. i dont need you, you dont need me, dont need to spoil each other's days. im going to spend fat bucks on food anyway, if you still give me fuck face then ill just bugger off to another place. easy.

if im staying for a long time to chit chat or do work in cafe then ill order drinks, otherwise no.
