You aren't entitled to get offended because I have better things to do than listen to you try and sell me something I neither want nor need, especially when I rebuff you with "no thank you". Perhaps one of us needs to go back to grownup school (and ironically, for once I do not think it's me).
Seriously considering skipping excruciatingly dull evening screenwriting class. Yes/no? Sitting in office, cold and bored and vaguely hungry but not enough to go spend money on food, especially as Chartwells stops serving actual food at 5pm (the same time I finish work). Not that they ever serve actual food anyway.
