Rather than making physical contact with someone who's a stranger. If it's someone of the same gender you know well like a family member then it's okay. But I had several guys try and do this to me when I was in a store the other day. There was a table behind me. I asked the woman at the counter to show me the stuff on the other side of the counter where there was more space. She refused so I just moved her whole table full of stuff back. Lol. Ppl are idiots.
