Seniors these days - they have no manners

Many people complain about teenagers or kids these days having no respect, manners, work ethic, etc. What I would like to bring to the table is that many seniors have also lost it too. Possibly due to aging, maybe forgetfulness, or it's just their blatant way of saying "I've earned my right to do whatever the f*ck I want!"

I will set the scene for you. It's Saturday night, not too busy but we know we're gonna get hit soon. Then it happens. BOOM! Everyone walks through the door at once. Not a big deal because my self and the other server can handle it. Then something strange happens. A older couple comes in and with a smile on my face I ask them for how many and they say eight. This posed a problem because we were full and we only had a couple of single tables left. Then they spot a reserved table and say "Wait, that might be our reservation." Perfect what's the name on the reservation. They don't know because it's a reso for 12 people, not 8 and it is clearly not for them. They start to sit at the table as if it's theirs. I explain to them that it is someone else's table and they should be arriving shortly. In a packed restaurant, it is chaos. Organized chaos, but still chaos. During this time the rest of their friends come and decide that they are going to tell me what to do to get them a table, which included:

• Moving a table from the other end of the restaurant to put it next to a couple of other vacant ones. I declined this idea because it would pose a fire hazard and no one would be able to walk down the main aisle of the restaurant. Plus it would still not be enough for the table of 8 they are expecting.
• Suggesting I go get a table from the back. What? We don't have spare tables lying around. They were shocked to hear that.
• Disrupting a couple that was eating and ask them to move all of their belongings and food to another table so they can have it. I started getting angry. I absolutely refused this because it is straight up rude. I said we have policies here that ensure our customers get quality service. I was not about the go and disturb them during their meal.
• Permission to disrupt that same table because they 'didn't mind doing it.' Absolutely not! If I am not going to move them then you are not going to either!

I turn around for a moment and there the old lady is disrupting the couple and pushing them to the corner. Then they move all the tables together, literally barricading in the couple and another table. The nerve. I go up to them and explain that it will be a while before I can serve them since we were very busy. Part of the reason why I did not make a huge effort to move people around, aside from being respectful to others, was because we were unable to serve them. We were already overloaded. So they can sit and wait for all I care and so they did. Finally, I got to them and guess what? That's right they all had coupons. FML. FML. FML. They did the expected complaining during the meal just because they could and that was it. They paid a very little tip which I don't mind coming from seniors because of many of their financial situations. But they didn't leave when they were done, they just stood there blocking the server station for what seemed like an eternity.

They are on my top 5 list of most annoying, disrespectful people I have ever dealt with in the service industry. Old and sweet? My a$$ more like senile and rude. Seniors these days, they just have no respect!
