Dollar General

Every time i go they dont have enough cashiers this last time i went the cashier named Billy got to me and said im closed and turned off his light its bad enough i waited 5 min. To pay but now i had to go to another line and wiat 5 more min. To pay i only had 2 items (2 chapsticks) i then asked the female cashier for his name he got upset and said what the hell did i do wrong . He then follwed me and my son outside and told me to stop being a bitter person. I think they need to start training these people on some manners and guest service this will be my last time i go to this location
