Shaz,
Lad is right, if you are worried about them choking because they are
drunk, cut them off. However if your concern is seeds from lemon wedges and
other things that can take away from the drink there are options. First you
need to take into consideration if the "garnish" is actually a garnish or just
garbage. Garnishes while adding to the visual appeal of the drink also add to
the flavor. Garbage on the other hand is for looks only. If you are using a
garnish consider juices to substitute and still add flavor. Roses' Lime Juice
in a Corona works just as well as lime wedge. Grenadine is a good substitute
for cherry flavor as well. Hope that helped.
