Allow me to educate. You DON'T ASK ANYTHING!?! Think about it, suppose you "tactfully" inquire, legally you "voiced" intent. I started out the same way, it didn't take long to realize, money was the ONLY language understood. Don't be stupid and flat out ASK for it or ask how much like so many have in the past only to be thrown out or worse, have the cuffs slapped on. Go in, look for their rate on the wall or wait for "mama-san" to tell you. All you do is add your SIGNIFICANT donation to the hourly rate, you don't need to say a word.
