So I took my bike to a "VERY RESPECTABLE SHOP" for a bunch of scheduled and non-scheduled maintenance stuff.

I noticed that they removed the tank vent hose.  When I asked about it, they said I didn't need it.  After thinking about it, I don't see a need for it either...

With the charcoal canister removed, does the tank vent hose serve a purpose?

No...

You still need the drain hose though.

Many shops connect the two with a Y to eliminate the possibility of fuel dripping on a hot header.

Is it possible for fuel to drip out of the tank's vent?

I have a plastic tank if it makes any difference...

If you raise the tank with too much fuel in it or overfill it enough so expansion causes it to come out.

The plastic tank has no bearing on it.

+1 on the expansion thing. I freaked when I saw a copious amount of fuel under my bike after filling up and riding 1 mile back to my garage.

If you accidentally overfill your tank and go around a turn at a high lean it may spew out. Best to put a Y like previously mentioned and route down to below the bike.

I've had it spew before on my bike. Combination of a hot summer day, and filling the tank too high and going for a ride in the hills.
