Bad customer service

Greeted by the cashier as if she had more important things to do , straight to the point I wanted chicken burger she just said we only have one without even giving me the price...to add my chips was cold and when I asked for sauce which wasn't even I'm my bag , I wasn't even asked if I'm eating there or take away anyway they said they only give on type of sauce ....the only reason I bought the food was to get the sauce I wanted
