sitting here in a tokyo internet cafe, reading the informative posters about cafe usage, and.... well.....

"do after a numbered ticket in the reception desk when you have this seat used"-?

"i may not have a question because the staff who is familiar with the computer and the internet is not in our store. And, approve the staff who can speak english in advance because there is no he, too"-kinda get the idea

"it is to abolish the thing brought from the outside that you eat and drink"-sound nasty

"it asks for it quietly when it talks in the store"-a very non-spieces specific rule

and on the bottom, in red!
"there is it to have the guest who cant comply with the manners leave a store, too."-youve been warned!
