poor service and the drive thru gets better treatm

Hi I have been at the store often and it is quite disappointing to see only one cashier available at the front, December was a very busy period and there was only on cashier who was selling the meals and also going to the back and preparing. It was only five people in the store wanting to buy and because there was no additional staff. we were forced to be served by one person who had to do everything by themselves. this was very disappointing and upsetting as we were waiting for a long time. You guys really do not care about your customers. the only service that was evidently good was from the drive through which seem to be serviced well on that day and it was unfortunate for us. I was there on the 24th of December 2015 and only because I was that hungry a waited. Please improve on your service as it is really ridiculous and we not there because we are bored we just want to buy and go.
