Having searched to see if this had been posted before and finding nothing I have decided to post this little glitch I found today,
The quest [Red Snapper - Very Tasty!] is one of the draenei starter quests, you get it at about level five just as you leave Ammen Vale. You need to get 10 red snappers, but you can only do it one fish at a time usually (every time i've done it at any rate).
However, as I was doing this quest, I got bored and deicded to use the net mutiple time, and to my surprise I got three Red Snappers from one pool. While it is just one quest, it stops you from wasting as much time and doesn't involve lag (I had 60 ms latency), therefore should be doable by everyone.
