Crazy Passengers

I was in San Francisco airport waiting for my plane arrive so I could go to work spreading joy and happiness by giving out cokes with a smile. My crew and I are waiting at gate 31 for our plane to pull up to the gate. We were scheduled to work 2:30 flight to San Diego. The 1:00 flight to San Diego was delayed until 2:15 and supposed to go out of gate 31 as well. If you do the math you know that we were not going to leave on time. There was an open gate at gate 21 so they changed our gate assignment from gate 31 to 21. Mass hysteria and pandemonium pursues. People come out of no where asking us whats going on. Ummmm They just said flight 1600 is now going out of gate 21. Hmmmm now the person standing behind that person comes up and says "which gate is 1600 going out of ?" Arggggg gate 21. This happens a few more times before we make our way to gate 21. I guess there hearing doesn't pick up the PA system or it's just my super hearing that allowed me to hear the three announcements that were made about the gate change. We relocate to gate 21 and take our post waiting for our flight to arrive. Out of the corner of my eye I see this elderly man and his wife making a bee line for us(we are in uniform which means please come yell at me). He is in a blue jumpsuit with a bucket hat and a mustard stain on his left cheek. He is carrying two bags and asks why the hell didn't they make an announcement about the gate change. I politely inform grumpy old man that actually they made three announcements. GOM says no they didn't and I politely state again they made three announcements. GOM takes the lords name in vain and states he wants to make a formal complaint because he had to walk all the way down to 31 and then had to walk back to 21. San Francisco doesn't have a PA system that goes throughout the concourse it is only in the gate area. With this information it tells me GOM was not in the gate area and the mustard stain on his cheek and the reeking onion breath indicates GOM was at the deli eating and then went to the gate at the last minute and learned his flight was now going out of a different gate. What GOM thinks is his flight has already left and in reality it still had not arrived at the gate. I had enough of GOM and pointed him in the direction of a gate agent and told him he would take his complaint. It's a good thing GOM didn't sit in my section and during the flight one of my crew members said that GOM hadn't stopped complaining since he got on the flight. All in a day of the life of a flight attendant
