I was at a shoe store (it sells more expensive shoes but are good for your feet) and this girl and her mother walk in and immediately go and stand in the line at the cash register. When they get to the front the mom opens her mouth and is basically already about to start yelling so the owner of the store has her sit and wait since it was only him in the store and there was a bunch of other people that needed to check out.
He gets back to her and the mom blows up because she had to wait and starts ranting to him about the store selling her daughter (who was like college age btw) expensive shoes and not letting her return them. It's an orthopedic shoe store so it's high end shoes most cannot be returned they tell you this and have signs.
But the mother carries on and the owner offers to exchange the shoes for another pair which leads to the daughter complaining about the first pair she bought. She trying on more shoes and the owner is asking her questions and she's saying stupid crap like "Well when I tried on the first pair I really didn't like how they felt but I bought them anyways." So yeah she's setting herself up as pretty stupid especially since the shoes she bought even though she didn't like them were $170.
Finally, they find a pair and this mom is going on about how she didn't get why the owner was so rude to her (he wasn't) and made her wait and blah blah blah. I had never seen such stupidity or people who thought they were royalty or something and should be treated better than everyone else.
Note: Salespeople can be pushy but at this store they are super nice. They do not pressure you into purchases and encourage you to find shoes you love wearing so it's not like that girl was forced to buy the shoes.
