One male colleague, here at work, invited me so far twice for a lunch and I turned him down on both occasions, I simply had other plans (Hooters and Paddy)...
And yesterday evening he asked if I have any lunch plans for today.... well, I told him how great guys you are, how delicious pub food is (sin to miss it) and that he must join me...
so here it goes - maybe not what you have in mind...
