Yes this is a rant...
I don't get asked this often (thank fuck!), but when I do a part of me just laughs and the other half just wants to punch you in the fucking face...
Example...
"Hi, I'd love to see you for 90 minutes."
"Okay, I am available at .....time"
"Well do you have a 90 minute special?"
...Does it look like I have a fucking 90 minute special?!? Do you think you're special?,(Probably, but I don't)...Do you see a 90 minute special on my website?!?...No...You don't...So what makes you think I should give you a fucking 90 minute special when someone else will pay full price!??...I wouldn't, so fuck off you cheap wanker, if you can't afford my prices then move on to someone you can. Don't take this piss!
...Okay, rant over...
