your staff dont know your daily specials and price

its amaxing how I will go to this specific fruits and veg, and half the time they don't even know their own specials and prices, I am tired of having to tell a cashier that something is on special at a certain price because u get to the till and they charge you higher prices, now I am calculating my bill as I shop so I can know when om cheated, and as I pay I pay for the combos 1st and watch the screen because half the time/all the time they will charge you for each item individually not as a combo and you end up paying more, then when you tell the person but this is a combo and at a less price why are u charging me more...they don't even have an idea that its on special>>>really? do you not brief them every morning on whats going on? its time consuming for us customers having to teach your staff your own prices then having to wait for manager to come and void the errors...love shopping at your place but your staff needs to get on with the program...and if your eft machines don't work please place a noticeboard, other than I shop and fill atrolley then be told at the till after scanning that cards don't work,,,waste of time
