Room smells like marijuana or hashish

Oh Yvonne, you just can't stop!

Oh Yvonne, you just can't help yourself!

Huh?
I don't understand what you are trying to achieve. Apparently, you are trying to make a fool of me. For whatever reason...

Just send a private message or just be straightforward?

Please be factual!!!!

All good, but thanks anyway!!

Another idea?:
To the OP, ask nicely with the police dog handler = raise suspicion?

It's meant seriously, the dogs always have to be checked again, maybe you could combine it with that.

One more tip: I would stay away completely, the dogs go off, afterwards he might think that you are the dealer.
