You stupid, ignorant, inconsiderate jackass, do you really need to stop your cart directly in the doorway of the Costco/grocery store to take a phone call/look through your wallet/ rearrange your kids clothing? Could you not have stopped to the side 6 feet before or after and to the side for exactly the same result without blocking absolutely everyone from using the doorway? Can you not feel the heat from the angry glazes of everyone around you coalescing into a singularity in your back like level 10 wizard-fire? If higher level wizards actually did their own shopping then one of them would have turned you into a toad. Harrumph.
