Lancaster centre disappointment

I was in the centre to buy things as usual n i had a sudden running stomach so I went to use the toilet I was in for 20 minute n the cleaning lady started knocking on the door asking me to come out she needs to clean and that it's not a restroom Mind you am a client and she she doesn't know me and her rudness didn't end there she kept knocking saying she is not going anywhere till I come out I took a deep breath told her to go call her supervised she comes back 5 minutes later they both start knocking on the door Am sorry to say the stuff had no respect for client that support they business am a business owner myself and to be honest the supervisor is just as illiterate as the cleaner how do you tell someone to come out because u need to clean am having a really bad running stomach and have to deal with such incompetent people if I was white this wouldn't have even happen
