Whenever guys ask 'am I free' I'm tempted to answer No I'm very expensive!
In reality they usually get ignored.
I sometimes reply with 'No I'm never free but I might be available, when did you want to book me for?'
Yes if its on the phone I will try sometimes to pin them down to a date and time and 9/10 guess what they seem strangely unable to commit...
Another one bugs me "are you around today" or "are you around this week" or "are you around next week" Its so fucking vague and annoying, I feel like replying with, well I am currently alive and well, but you never know I might get struck down by lightning, have a heart attack, fall down stairs and be crippled for life any time now, so when exactly did you want to book me, and for how long?
Also the "What time do you start in a morning" I've said to a few , well it all depends when I get a booking as I can't really start on my own now can I?!! ffs lol
