No, this isnt how begging works.
Imagine if you were in a busy marketplace holding a sign saying "GIVE ME FREE STUFF PLZ", no one would give you anything. The way to beg is to pressure people into doing it. You say "excuse me, but can you please give me something for my birthday?" and the pressure from asking them directly often leads to free stuff. You're not gonna get anything off of a thread like this though, lol
