I knew someone like that too. Liberal chiseler who always messed around with the wait staff and tried to get freebies and price reductions. His wife was a Federal employee
Their own? You have got to be kidding me.
I wouldn't put it past some of these to be running a double scam- there on "official business" so someone else is paying the tab, get the cost reduced or the meal free, submit the original bill for expenses, pocket the difference!
I see that you have met my older brother.
I do not go out to eat with him anymore, he always tries to get something for nothing and it is embarrassing.
