pregnant and treated like im nothing

Shopping at Edgars pitchard street in JHB CBD was horrible today,the 50% sale was on from the 8th October 2015 yesterday so I decided to pick few things for my unborn baby as much as the store was packed I told myself I will do the shopping fast and leave but the que was soo long when I que at 13:00 but I decided to wait as I have shopped in bargain saving almost R1500 from my shopping at 15:00 I was pressed I needed a toilet the lady behind me suggest I go to the front but because ever since I'm pregnant I never do go for special treatment (though it was required and allowed ) we stood there but I could feel I can't go no further that's when she went and explained to the cashier who said I should come so to be sure I pulled my trolley to the front but I heard people whispering \she will not pay before me
