We got about a half-dozen of these at my Catholic Church.
After Mass they come streaming to me, a lowly usher, with their complaints. The Priest is doing this wrong, the Liturgy should be done THAT way, etc.
I look like the Pope apparently.
I guess you look Argentinian.
Since you let them scream at you, complaining, YOU are to blame. You obviously answer them too, otherwise they wouldn't keep going back to you.
You know what to do to stop them. You don't do it though. It's not your job as an usher, which is NOT a lowly job, to have to listen to that. You COULD tell them to take it to the priest. Maybe one day you will.
Our ushers are great. One old guy has been doing the usher-thing since 1955. He IS really old.
