for me, so far, while I have been working, I've had :
1) Ppl scolding vulgarities at us and refusing to pay due to a 'defect' with the keyboards, claimed that there was no sound when he pressed hard, and I mean very very hard. The worst thing is that they were adults in their late 20s to mid 30s. Totally behaving like kids!
2) Ppl bringing drinks in cans, packets and the worst, plastic, into the studio to drink, and guess where do they throw them when they're done? You guessed it. They just throw them all over the room.
3) People deliberately jumping on the bass kick and causing the skin to tear.
4) Last minute (like 11pm at night) book 1-2am jamming, then in the end refuse to end the jamming, 15mins later coming down to tell me they want to extend till 3am.
I still do try to keep a smile on my face even after those things happens, as the customers are in the end, afterall, top priority. Other than that it's been quite pleasant working. I do enjoy the short chats with customers when they enter/leave the studio and also bands that play great music, new or old.
liquor and beer into a studio is a must have. i think the jam folks need to invest on a a small ikea table or shelves to we can put our beer/booze on it \m/ and 1 more thing. !
Yes, beer and all is nice, but you have to understand that it'll cause more problems. Some people are disgusted by the smell of the alcohol and have a bad impression of the studio. Also the people who drink may become drunk and who knows what they'll do. All the rules are set in place for different reasons, please understand.
