When shopping at Harbor Freight Lexington NC and checking out I was asked to provide my phone number, I declined and stated "I get to much junk mail now", the girl smirked and said "we dont sell your info". I stated to her, yes you do share my info when I give you my telephone number. She then stated you are full of "[censored]". I made a decision to never shop here again and have to deal with an attitude when I am paying hard earned money for tools. I researched my information and found that I was correct.

Recommendation: You can buy better products at local stores without the negative attitude and foul language.
