Speaking of meetups, I once saw a gathering at Hans cafe back in around early 2016 or late 2015, can't remember. Around 10 of them I think and it was over midnight.
Kits, mods, ejuices were lying among with their drinks and I think there's some snacks too "on the table". Everything was openly displayed.
People were staring with strange looks as the vapour produced by them seems to make the area look like genting island.
Not to mention, the smell were entering the cafe whenever customers enter or exit that door. Overheard a few people asking "is that shisa?"
