Solution:

To get the water into the glass, the bartender performed the following actions:

1. Sticking the match into the lemon wedge, so that it would stand straight.
2. Lighting the match, and putting it in the middle of the plate with the lemon.
3. Placing the glass upside-down over the match.

The burning flame consumed the oxygen in the glass, creating a small vacuum, which pulled in the water through the space between the glass and the plate. As a result, the bartender got the water into the glass without touching or moving the plate.

Clever, hah?
