plus free gum is always a win

Exactly. They sound much nicer than some coworkers who'd probably just laugh about it behind a persons back.

^you never know if they do. they are probably like "omg I spend half my paycheck on gum for this chick. shit!"

That's not always the cause of bad breath. It could be a health issue.

I had a coworker who brushed his teeth regularly but it didn't help his death breath. We ended up doing the same thing as OP's coworkers, giving him gum frequently.

Acid reflux is one example of how health issues can affect the smell of one's breath.

I agree. OP should just take a mini toothbrush or mouthwash to work, probably some floss too.

as oposed to the bad way - throwing OP out the window?

Or like meanly telling him his breath sucks or insulting him.
