Treat customer s with respect

No customer service at all cashier's do not greet not even a word of thank you, the only thing they know if you've purchased something on promotion they keep you waiting and shout "authorize" without informing you ,I had to swipe through their speedpoint And was told my card declined when I knew there is money in my account, had to go to an ATM and withdraw and give cash however no apologies or even a thank you after having to run around, well I feel they need more training on customer service
