who made this sign?

This is like when Walmart marks up an item and then brings it back down to the original price temporarily and calls it a 'discount'.

this was probably made to target drunk people who can't process stuff in their minds properly

That is well made scam ove there.

I believe it's called a joke. I haven't seen many on this site, at least not funny ones.

i think they mean you buy 2 get one free
