Like when dealing with kids before they get too excited:
NOs
No boost inside (fly safely, don't fall on your knees);
No dealing (no selling, and better don't ask awkward questions);
No pics from ppl inside (this ain't no zoo bro/sist);
Now my experience:
I forgot the batteries of my vape, my concerns started to arise till I saw devices to smoke on sale, which made me ask the welcoming-gorgeous girl on the counter if I could purchase something similar to smoke with (I showed my vape), a wise question was asked: Do you have your own weed? I had it on my Wizard of Oz creation, so she introduced me to the Mr. "volcano".
I nodded several times while she explained me how to fill that special balloon. Was I keeping all the info... Nop. Once I topped the filter with my own spices (green Maple leave), I started scratching my head, 4:20 seconds after, the gorgeous girl was directing me.
Did I have fun seating at the bar by myself? I couldn't be with better company (wink).
