Went to exchange 2 propane tanks. Asked cashier if matters if I have blue rhino and they have different brand. He says no. I pay up front. He hands me one set of keys because he is unsure of which works for lock. I try them. None worked. Go back and say none work. He gives me another set. One key out of set fits but won't turn and now won't come out. I tell cashier 3 times and no help. Even one customer saw my issue and says go back in for refund. I try again and blister my fingers. Finally give up. Bring rest of keys off ring inside and say that none work here is rest and one key still stuck. Frustrated, I take my 2 old tanks and leave and don't bother wasting more time or arguing for a refund. They just made over 40 bucks of free money because of poor service and sure don't care.
