Cute shop. Obnoxious salesgirl. Asked her for "x".Kept showing me "y" and insisting she knew what I wanted. Not a huge deal but when I tried to explain what I wanted (again) she snaps and says: "I've got you" and shows me "y" again.
If you're going to attempt to make your customers feel like idiots please make sure you know what you're talking about.
No need to be snarky.
