POS systems

When I went to the Asian store to buy some food last week they said they only would take cash. I did not have any cash all I had was my debit card. I did not see any ATM machine there but I did not want to get money from it I did not want to pay a service charge. I think the store needs to get POS systems so that they can start taking debit or credit cards from their costumers. You know not everybody right now is carrying cash in their packet. I ended up going home with out any of the foods that I like. It was okay I can come back there again later when I have the time.
