She refused to assist

Me and my hubby Just went to mac Donald bruma, but we had a concern abt the sauces in the mac feast meal. hence I once bought and my burger was very dry for me to swallow..The lady glady's was call by the cashier to assist...before she could even approach her attitude said it all, she rudely as her cashier wht are you calling me for. she then said with her bad attitude we can take our money if we'd t want it that way and take our money cz she cnt do anything...I asked cnt she put enough sauce...she was rude and started countING our money as fast as she can cz she wanted us out of her side...she was so rude
