Staff have no clue about products offered

Your stores are getting more and more of an irritation than a shopping experience. From waiting up to 45 mins to get a delux breakfast as there is none or just one staff member behind the hot foods counter to staff that know nothing about a service that you offer. Please see pic CH2 where at the till, where I made the cashier stand up and have a look as she tried selling me Checkers vouchers and not Uber voucher. Look at CH1, not sure if she is a manager, but also had not freakin clue what I was asking for. So on God's green earth, can you please explain to me why you "buy your uber credit here at the till" but I get cold fish eyes gazing back at me? Please don’t come with the story about your staff rotation is very high... You should then be asking your self... Why is all the staff leaving Checkers East Rand Value Mall so often... Surely there is something that needs to be investigated there.
