Just kind of a weird question.

I'm in Rome right now, and tomorrow, I will meet with friends with two young kinds (7&9) for the remainder of the week.

I know that at some point they will want to have some of the toys that some street vendor sell (especially the ones that have lights).

I don't expect the toys to last more than a couple of hours.

Is it safe to buy from them (the act of buying)?

Thanks,
