Double Felwood Food!

Ok most every player should know by now about the felwood foods. Whipper root tubers,night dragons breath, windblossom etc.
They are very handy in pvp and pve as the whippers and night dragons are on seperate timers from regular healing potions so basically u can heal yourself for 1750(major healing)+900(whipper)+450(night) for a whopping total of 3100 health. they are also only on 2 minute cooldown.The best part is they are free!

Well i found that if u find a plant with the food in it, u open the the dialogue box(after cleansing it if needed), zoom in so there is minimal distance between the message u click on and the plant. left click the message to get the food as normal, then quickly right click the plant again. about 50-75% of the time if u did it fast enough another dialogue box will appear and u can do it again and get double food.
Not sure if this has to do with a laggy server but it works all the time for me on destromath and illidan(both fairly high pop servers). Im not sure if this was ever posted so i figured i might as well spread the word. Ive been doin it for a couple months now and i can easily got 100+ whippers in about 30-45 mins(after farming for soul shards to get the plant salves). Ive actually gotten it to work 3 times on one plant before as well. Also im not positive but i have a feeling the plants become corrupted when they sit out too long. Ive actually ran back and forth for an hour gettin the plants as they spawn and 95% of them werent corrupted so i didnt have to use any salves.
