I do not drink alcohol or smoke.

When you hire me:

I choose not to drink, in fact I rarely have a chance even when I’m not entertaining at an event like yours.   Would you offer a beer to a wedding celebrant in the middle of the ceremony when they’re working? Would you be OK if a surgeon joined you for a quick whiskey while you were lying the table?  Even the bar staff at your venue at your venue don’t partake while they’re working.

I won’t be drinking, I don’t smoke, I won’t even stop for a meal.  I focus my attention on your event.

Alternative:

It may be hard to believe, but some entertainers expect meals and alcohol to be supplied as the night proceeds.  Some even suggest they work better after a few beers.  Just like a surgeon or professional driver, right?  If it’s OK for your DJ to have a few, who then is responsible for deciding when to say when?  Who is responsible for their trip home?
