Swipe system outdated

I have bought diesel and petrol at BP at Port Elizabeth Gelvandale and was told by the attendant that I need to swipe separately for these fuels as their system doesn't allow for one swipe for both products. BP standford road in Gelvan Port Elizabeth I find this very annoying that the customer must be charged twice for the transaction due to your inability to update your software to accommodate one swipe for all fuels as most of the other service stations can do.<br> This type of transactions is not in the best interest of the customer who must pay more on service fees to the banks.<br> BP i suggest that you get your Software people in or ask Sasol how they do it and just copy from them. <br>
