What's the Word for Wishing You Hadn't Asked a Store Clerk for Help?

Want to invent a new word?

I need a word to describe that feeling of  regret you get when you go into a store looking for something, ask the clerk for help, then realize, not only are they not going to help you find it, they are going to slow you down or try to prevent you from finding it yourself.  Got a noun or adjective for that?

Retail regret?   Storensnarement?  _____________

You have one?
