Unsure what you mean? With the current EPOS system the only mistakes you can make is taking in and dealing out the money. Of course some bets still dont go throug the system so you must manually settle them, but normally there isnt that much problem with this.We had a problem once at a betting outlet. I forget what sport/event/match it was on, but we stepped up to the counter and said something along the lines of "we'd like to place a bet on this". However, the person working the counter drew a blank and later we realised that when we are to make a bet, we should just put forth a number which they'll enter into a computer, our bet showing itself on the monitor to them.
