Bad service as I could not get help for a toilet

I went chicken licken in klipfontain and I bought my meal being pressed and I requested a toilet 🚻 and I was told I cannot not enter as the lady didn't even wish to assist me and I asked if is there any alternative as I will wait for my order and am pressed and I need to go to the loo and she said there is nothing she can help me with I have to make a plan by myself Her name is Maria
