Customer have no shame

Not once have I ever gone into a store and outrightly say "oh this is so expensive, I got this cheaper somewhere else", especially to an employee (I lied. I did that with buldak noodles once, but it was under my breath and to my friend).

Like who goes into a store and beckons employees like dogs, and examines each and everyone item and complains about each and every item saying it's cheaper somewhere else?

Once this old lady and her sister examined one of the shirts and went "oh, I can get this for $7 with two" directly to me is when I went "that's great. Why are you here?" (I'm one of the owners, so getting fired won't be an issue with me) And they walked off with disapproval.

No respect. No sense of awareness
