Am i just too nice or what?

You seem like a great person, but you do need to be a little meaner, I'm not trying to be mean, but, you do seem to be too nice, next time something like that happens, as soon as it starts, yell for the manager, and that should stop them, or you could slap them, you would be totally in the right, because that is ual ault, plus if you asked them to stop, that's ALSO ual harment. So, next time, you can be prepared.
