Yes, you can! It’s free.
There are many pocket tissue distributors on the street especially near station. This is a advertisement of company. People can’t pretend to have a simple flyer which might be garbage on the street.
But, If you would be distributed something useful, you will have one definitely. That’s the point. Convenience stores have one, but it is not so cheap. Get one if it is free and a distributor will be happy to reduce one for his or her work quota.
