Clerks uses fowl language and swears at clientele!!!!

I went to the shop at the Merlot center in Tableview, Been going there for 6 months and they never have Peter Stuyvesant Blue, I mentioned that to the clerk (scruffy looking gent with badly painted nails and an attitude of note, When I mentioned they never have the brand I am looking for he straight told me "BUL****". Now I have no issue going across tp the spar to get what I want, the principle is that you do not treat clients that way.. I am personally never going to that shop again and will advise my entire family and friends to avoid them as well.
