Dude, I have people eating full meals in front of me during
project discussions, and I'm not affected.
I have people chugging down cappucinos and chicken pies next to me
in LT7, and I'm not affected.
And seriously, I'm not affected at all by all this eating and
drinking going on around me.
If your friends say that they don't mind, then they shouldn't be
affected, either. If they are affected, then they've got to work on
their willpower.
So just eat, drink and be merry - steady boh?
