This is much funnier as a commercial than when it happens in real life.
First off, the guy in this coupons dot com commercial looks pretty clean before he washes his hair in the aisle. Before someone is desperate enough to do this they have usually gotten pretty rank even by their own standards. Second, think of the slippery floor, the potential of a lawsuit and the effort it’ll take to clean all the suds off! Third he then would take off to the free sample area (which this company has another commercial about) using his hands to stuff as many as possible down his shirt while trying to elude store security.
This commercial gives me PTSD.
