Another gripe.
Band member (instrument immaterial) "Can I borrow some Gaffa tape?"
Me..."When do I get it back?"
Band Member "Do you have 5 batteries for my various (unnecessary) foot pedals"
Me..."Yes"
Band Member "Can I have them?"
Me..."No"
Finally, Could drummers please not rehearse their seminal 15 minute solo, whilst I'm attaching microphones to their kit. A punch in the face often offends.
