I think there's a lot of variation depending on the culture and context (i.e. this is a single impersonal transaction with an almost zero chance of repeat business, and probably attracts a lot of sketchy people to begin with). Many places in the world are poor but you don't feel live everyone is constantly trying to take advantage of you (but of course, the opposite is also true).
