Probably not the best experience for your first gig, but as Hee Won Jung pointed out, shit like that happens. Being devil’s advocate, the bouncers have a responsibility to throw those kind of people out, but there isn’t anything you can do about it. Thing is though, considering you got such a good response, I wouldn’t really worry about it.
At the end of the day, the fact that you got great response, and really enjoyed it is a great sign. You’ve gotten a taste for it now, and once you get that, you’ll have the passion and drive to improve your skill, and go out hunting for that buzz again.
Congrats on the first gig all the same. Onwards and upwards buddy. 😉
