Act something like this:

pawn Код:

new lastRobbed[MAX_PLAYERS];

// in the command
if(GetTickCount() - lastRobbed[playerid] < 120 * 1000)
    return SendClientMessage(playerid, COLOR, "You must wait 2 minutes before robbing again!");
lastRobbed[playerid] = GetTickCount();

You could also make it using PVars since this data isn't often accessed.
