Like Tony, my opinion changed from your first post to your follow up.

Min. Purchase requirements, employee to customer attitude, closing shop early and running folks out. The management of this establishment sounds more like this is a hobby business than a professionally run joint.

I'd shop elsewhere.

Having no B&M close to me, there are a couple I use an hour or so away. Both have lounges, and I've come to know owners and managers by name at each. They know I'm good for purchases, and neither have ever questioned me on what I'm smoking or where I bought it. If I'm in their area and want a break I may stop in and smoke something I brought. Other times I may purchase and go and not enter their lounge. The key difference between them and yours is that they try to make their patrons as comfortable and be as friendly as possible to gain loyalty. Yours just seems to feel that the customers owe them something.
Placed in your shoes I'd buy from online before giving these clowns another dollar of my money.
