I am wondering if anyone here has it where they have to before they leave someone, touch their skin like their arm or their hand

believe me: it's a weird thing asking someone behind a shop counter or a random member of the pubblic "can I touch your skin?"

if I don't touch the person's skin, then I get this feeling that the person doesn't like me, they are going to be in danger, (like fall when they get home or something), and it bothers me for ages- like, " I didn't touch this person's skin, I'm a bad person"

anyone else
