Rude Shop Attendant

Went into the shop asking about shoes in their display and was told very rudely that the shop is an optometrist and not a shoe shop, then i asked but why have the shoes displayed then? And Samantha then told me don't ask her ask the supplier, I asked for the suppliers number then i said i would maybe put it on social media (meaning where to get the shoes) and she took that the wrong way too telling me that i was being pathetic and ridiculous!! Shocking really! Would not set my foot in there for any reason in the future.
