Family Dollar review: customer service

I visited my Family Dollar Store in Oshkosh Wisc. Only to be discouraged standing in line there was 7 people behind me, and one clerk to check out, When I asked her if she had help, she stated that the manager was unloading the truck, the store I work at has a rule, of 3 or more people in line you call for help, With all the store robberies that happen, most recent Green Bay Wisc. there should be 3 or more employees in the store .
