Whose fault is this?

Read from right to left

I took this photo at a restaurant in China. Should the person who made the sign be held responsible or the person who is in charge of getting the sign made? The manager who oversees the entire process? I think everyone involved is at fault.

Any one of them could have took the extra effort to double check the spelling or run it through a spell checker or realize that English isn’t read from right to left.

Does this count as a case of Not my Job?
