Tell somebody they have bad breath anonymously.

This Doctor will send your stinky buddy an email, on your behalf.

I’m sure he thought, it would be a good way to help others and also get some free advertising for his breath remedies. But, it could easily be abused. People submitting names as a joke.

Also, if the reason you haven’t told your buddy he/she stinks, is because you don’t want them to be embarrassed, this isn’t going to help.
