Rude & bad customer service !!!!!

BP Petrol Station 381 Rivonia Road, Rivonia - I've just had a rude experience with the pregnant woman working behind the food counter - her name is Abigail. I ordered Russian & chips. I wanted to put sauces on the chips, in which there are a number of bottles of sauces on the counter. As I started putting the sauce on, she GRABBED my hand & said in a VERY rude and LOUD tone \These sauces are not allowed to be used for the chips - there are sauces on the table"and pointed to another table in the shop !!!!! Because of her rude action"
