Tell me the better expression

[Glamdring]

Sakura, the phrasing isn't the issue, it's the "please". once you have that down-and you do-it is no longer a matter of phrasing, it is a matter of courtesy on the part of those you are addressing. In your examples you are 100% handling things correctly. Unfortunately, there are a large number of players lacking in courtesy, and many of them use the supposed language barrier to hide their rudeness behind. Keep conducting yourself exactly as you have, but once you are answered with discourtesy you are under no constraint to continue being courteous.

Edit: and I wish I had the facility with Japanese that you have with English.
