I was trying to figure out what year the pics were from. I love guessing, so i am going to! I think the one with all the people eating inside is most likely somewhere between '88-'91, or maybe even '92.
yeah, late 80's / early 90's looking at the people in the first pic...
guy in the 3rd pic looks like he's been watching over that cart as a favor for someone on a 45 min bathroom run... and he's about to walk
