Disabling the rob feature if someone is depositing or withdrawing money

Hmm, ofcourse this is what usually happens in real life too and it's not something wrong. - 1

That may be bad for u, but for the other person it's an opportunity to rob you and earn. Just learn when and where to deposit money. No need of this IMO

If you deposit money around ATM in ammunation and san andreas police departments, it is logical players rob you, because you deposit money in zones with many players...deposit in others ATM without players around.

Nah

Yeah, being robbed while using an ATM sounds like something that would actually happen...
