Irritating BEX systems

So…yet another irritating systems hassle from Builders Express Bryanston. I bought a Lottery ticket there twice this week. The first time the cashier ran after me banging on my car window to get the ticket back so she could copy the ticket reference number ! Thought it was a mistake. Bought another one today and not only did the casher get it wrong (I wanted one line two draws, got two lines one draw – is it so difficult??) but then I had to wait nearly five minutes while the ticket was taken to another cashier on the main administrative system for copying in the reference number. She of course had to deal with all her other customers first, so I wasted five minutes waiting. Well I suppose it gave me time to complain to the manger who said ‘it’s the way the system is designed’. But WHY ? No-one else does this. Just like no-one else makes you fill in a manual register when you swap out your 9kg gas canisters. What is it with Bex and these irritating delaying systems ? Surely systems are there to serve the customer’s needs first ?
