Let me get this straight.
A security guard tries to stop someone from going into the team parking lot. The player identifies himself, and then walks by.
The first question I will pose is this.
Why don't the players have ID badges? Expecting the security guard to know all the players by sight is a bit ridiculous. It was an honest mistake. I would venture to say there are quite a few people here on this board who have IDs for work, perhaps a sticker for their car to park in the lot, and maybe even a card swiper to access the lot.
Second, how would a security guard stop someone who did not belong in that lot as they tried to pass. Unless the security guard is Superman and uses his laser eyes, you reach out and impede the progress of the individual.
Last, Williams shouldn't be rude to a guy doing his pinche job.
