Is she for real?

So I'm at work and I get called to the front of the store to help a customer. I find this lady holding a tea pot that has a weird mark on it. She tells me that she wanted this tea pot but this was the last one and it had something wrong with it's appearance so she asked an employee for a discount. She then told me that she "had been in the store only 20 minutes and she heard this girl swear twice, once while she was marking it down for me 10% (which isn't enough by the way) and another time. She didn't swear at me, but she swore." Now as I'm about to laugh at the lady because I think she is being ridiculous already she asks me for more of a discount because she heard our employee swear. The silliest thing was she was totally serious that it offended her. I later asked the girl what she said and the word was shit because the machine that makes tickets is sometimes finicky. Some people are silly.
