Aside from the fact that many of the people in the food lines are NOT HOMELESS.
YES. Anyone can line up for food.
But there are ALWAYS people there who play games and disrupt things no matter how "under the radar" they may be.
Here are some of the things that happen.
GET LAST PORTION
Person knows that servings are running out, asks for extra order for person that can not get their own.
This was planned ahead. Gives that person TWO SHOTS to get LAST PORTION.
Intent not to get last portion for self, but to deny portion to person after them in line.
HOLD UP THE LINE
Once a person has their serving they will be more than happy to take ALL DAY at the very front of the line.
One guy put THREE different salad dressings on the same salad.
One guy stood there looking around the place.
SET UP A FIGHT.
And make it look like the other persons fault.
One way is to NOT move forward in line...EVER...making the person behind you step around you.
Then they make a loud noise and claim YOU ARE "CUTTIN."
Another way is someone that person DOES NOT EVEN KNOW walks up to them in line acting like they know each other and are having a friendly conversation.
Both people are having fun KNOWING that the person that walked up is taking cuts in line, thus making it take longer for the rest of the line to get served.
BUT, the real kicker is knowing how much it is upsetting the rest of the people behind them in line.
People at the front of the line like to think that the coffee area is an extension of the principle food line, this way they can hold up someone just wanting coffee.
When at the coffee area some people will keep shifting between the coffee pot and the sugar area to try and block access to ALL the components of the coffee area to as many people as the can, for as long as they can.
As I do NOT write these down, I can only recall a few now but there is a new one almost EVERY TIME I AM IN LINE FOR FOOD.
Two or three times a day.
AND NOT LEAST
There are people who show up purely to cause trouble.
NOT every time but many times.
And in some venues it is ALL THE TIME.
