I take many things for granted when I eat at restaurants but of these, two are proving exceptions here in Hong Kong: water and napkins. Tea is the norm to drink, not water, but I've found it hard to even summon up a glass of water ("we don't have ice" was what I heard at one place). Hot water, ostensibly for tea, is easier to come by. Napkins, on the other hand, I don't have any theory for, but in two restaurants I've now been not offered a napkin. I happened to have a towel with me, so no big deal, but not getting a napkin with my place setting, and not being able to get one when I ask, is just weird. At one place I could blame it on just them, but now that it's two, I think I need to bring my own napkins whenever I head out.
