Dollar General review: Customer service

Was in dg in humboldt, tn. On mothers day. Line was backed up...10 to 15 some with buggies full... Only one cashier. Mgr, came up and said district mgr told them not to open another register unless at least 13 in line. There was also another employee there putting up stock. We kept complaining till she sent other girl to open the other register. Mgr got smart with another customer who was behing me. Not a good way to treat your customers
