I'm going to ask someone who can't stop burping to be quiet in a library
Is it really that much of a problem.
Yes, I will do anything to get rid of this disturbance. I'm tired of his bullshit and I can't concentrate.
Burping constantly is a huge problem when you need to read quietly, I can relate. He might have a health condition, try to wear headphones first to see if it helps. Or you can move to a different area of the library too.
I know, but do you think that he will ever stop disturbing everyone?
Eventually it has to stop. If it keeps going on, talk to the librarian they have the power to remove the person so everyone else can study in peace.
