This is acceptable in my country. Been told I was being rude for not doing it. I hate unwanted physical touch but must continue do it...
My culture is slighly different, I guess. In my home country, you're supposed to kiss people on the cheek one or two times in certain ocasions (although I'm still not sure when it's appropriate to do so, so I just let the other person initiate if they wish to do so), or you could be seen as being rude. It's especially a normal thing to do in familiar setting, even if you have never seen or heard of the family member. I never panicked when I was kissed on the cheek, but it still makes me feel uncomfortable. Why it is rude to not kiss back, that is something I have never understood. Actually, I find it somewhat disgusting and distressing. "Isn't that something that you should only do with your family and *very* close friends?", that is a though that always crossed my mind and I discussed it with my family many times. When I was younger, I would avoid it at all costs, unknowingly that it would be seen as rude, and I had a few ocasions I was told I was being rude (very directly), and since then I've been trying to cope with it by letting people kiss me on the cheek if they wish doing so and attempting a somewhat awkward kiss on the cheek by my part.
This part of the culture is annoying and I hope it can change with time, but I don't think I want to stay here much longer. If I had enough resources, I would leave this country already, I don't feel much connection to it aside from my language and family anyway. I still feel somewhat like a foreigner in my own country. I also hate the overly hot sunny days that consist most of the year. I don't have a problem with hugs and actually crave for it sometimes when it's with females, but when it's males I don't feel comfortable at all. I wished head pats where a thing in family setting but it's reserved for children. I wished you could just bow in polite situations. Shaking someone's hands is something that I don't seem to do a lot of the time, I think males do it more times between themselves in polite situations. In informal situations, I think they do hand shakes or pat their shoulders or their back. When it's female and female, you can hug (informal) or kiss on the cheek (polite or informal), when it's female and male I think you should only kiss on the cheek, or do nothing, but, as you can see, I'm still somewhat clueless (it also depends if you're a family member or not). Not only that, but you also have to know the level of intimacy to know how to adress the person, and sometimes it's tricky. I usually just call strangers in a polite way or by title or by their name with their title, but sometimes it's difficult to access the situation, so I might call people whose age is similar to mine in a polite way as well.
