Someone left this message on the wall at Saizeria

So this was written on the wall of a saizeria restaurant I usually go to.(please dont argue how bad or good saizeria is)
I noticed it on my 3rd visit and now this seat has became my favourite.
The text is :(Translation below)

“この席を共有した
方々へ幸あれ。
ありがとうの反対語
は当たり前
当たり前とは？

ありがとう🤍
まじらぶ🤍

Thank you”

Translation: (feel free to correct me)
“I wish all people who shared this seat happiness.
Taking things for granted is the opposite of gratitude.
What is granted?

Thanks
Much love”

It seems that it has been there for a long time,
I wonder if the restaurant staff left it there as is intentionally.
