Hi Tiger 
I would tell him to.....well you can imagine. That is rude and is beyond unprofessional. I agree with some others. I would not return without an apology. I had a similar experience at a local vape shop here in my city. The owner was a bit rude after we walked in with our SB's in hand. Of course people asked where, how, what, etc? I shared and I am not a vendor by any means. I also do not believe in knocking any products as long as they are helping the user stay off cigarettes. Sad thing is my hubby and I could have been regulars out of convenience but he blew it with me. I am sorry you had to deal with this persons behavior toward you. Hopefully the person will come to their senses and understand they did wrong. (hugs)

Amen to this statementSounds like because of this forum you were better informed than he was and he felt threatened. Ive had people working at brick and mortars and even online vendors automatically assume that they knew more about vaping than me and I rarely do business with them from that point forward.
