Rude and unprofessional cashier

Last night I went to get dinner at nandos save ways centre. The lady doesn't ask which portion of chicken I want. After ordering I request a leg portion as she didnt ask. She literally makes a joke of me with another cashier that I insisted that she should have asked me. I found that to be utterly rude and unprofessional, im 38 weeks pregnant and was tired. To be made a fool of was uncalled for!! Her name is Juliet J. I bought at 19h59 on the 1st of October.
