I tried that as well, but stumbled upon the same problem as you in that it wouldn't cancel itself.

If you want it to use an item as well, then put all of the first common event in a Conditional Branch checking for the item in possession, and then the second common event just taking one of that item away (you could, if you wanted, give the party an "Empty Beer Bottle" item, which they can then trade into a shop for 5g or something. Just for the fun of it. ).
