I am a professional piano player who plays in several piano bars.
I more or less am a freelance rock n roll singer and travel wherever I am hired to and whatever pays well.
But the one thing that is a must for me is that whatever bar I perform at must have the highest quality and modern central heating and air conditioner! Because having superior indoor comfort is quite substantial for me to do my music and play my best. If I do not have good heating and air conditioner I can not perform as well and the folks that hire me would not be glad with that, and neither would the folks who are coming to the bar to hear me and drink. This is why they all know that if I am to be there, they better get their heating and air conditioner in perfect laboring order. If it is not in perfect condition and of the utmost top quality and modern they will immediately get it fixed before I am even supposed to be there. This is something I tell them all up front. If you want to hire me, your central or ductless heating and cooling system must be fully laboring and be the unquestionably best so I have complete and absolute indoor comfort while I perform. There was only one time I can recall in recent years where the heating and air conditioner was not laboring officially. I ended up quitting that gig before I even got started and walked right out. I would rather lose some currency than play in discomfort.
