I handed Monica a 20 dollar bill and said my pump number she said ok then I went outside to find out the pump wasn't working and I went back inside to inform them about it and they said my 20 is too old but it is real and that I need to give them another one then she gave it back seconds later saying my real 20 dollar bill can't be accepted.. I always face discrimination but this is beyond my handling point.. she refused my money after admitting it was real for no reason at all this is really really unacceptable.
