All joking aside this man will clean Home Depot's clock before this is over with....
Possible, but not likely. It is entirely possible he is responsible for the glue to set up HD. Even if he gets a settlement out of court, the attorney will get the lions share of that. HD probably did nothing criminal because it was not intentional. Only the outrageous successful suits get the headlines,99% of these just go away or are unsuccessful.
I also think he will collect handsomely from HD, not because they took too long to take him seriously, ( which could be their fault) but because there was a toilet seat (in the HD washroom, I take it) that had Krazy Glue smeared on it (while this is not technically HD's fault, one of the HD employees could have done it as a prank.) HD ironically will wind up paying for THAT. Especially since the guy fainted.. I say settle for a quarter mil.
