Fk yeh - a colleague is a notorious 'close talker' and eats
heavy garlic laden food every lunch time. We are talking almost touching noses when he's exhaling curry breath into my own O2 intake! [}:)]
It is kn unbelievable at times, and I have fallen victim and seen other colleagues back away repeatedly, until cornered or unable to retreat and wincing in discomfort and holding their own breath.

One day it was sooo bad and making me increasinglt tense my blood pressure rose to the point i thought i might just shove the sod away or pop him on the beak.

I literally had to bump/pass him to one side (pretending i needed a stapler or sumpin) and take a deep breath!
The bloke is a nice sort of chap, and all concerned have tried not to offend, but his own habit is extremely offensive to most.
I eased the topic out there some time back, aluding to someone else's similar habit, and I think he got the drift as the situation has lessened but everynow and then it is back to eskimo kisses and get me a barf bag!!!
