Hey,
Needed a script to get myself from 5-25 thieving and none of the ones posted worked so I put this together in about 5 minutes.
For some reason MakeCompass('N'); does not work for me, so just start the script standing below the west stool by the tea stand and make your compass point north, then it should work just fine.
Very basic, just steals tea until inventory is full and then drops them. Tweak to your hearts content.
Edit: If you're having an issue with it not clicking the tea stall either tweak your compass angle a little bit or use the color dripper and change the color value here:
if FindObj(x, y, 'ea', 7045003, 10) then
