It’s because of signs like that there’s been a military coup!
As regards the OP, that ain’t posh, there’s so many ways it’s a cheapskate operation. The sensor isn’t exactly in the middle of the tile, neither is the sign, they’ve used cheap screws with plastic covers on, instead of chrome-plated brass domes.
Shoddy workmanship, they should be ashamed of themselves!

This was in a bar in Prague. Wazzing produced a delightful citrus aroma.

We installed wave on controls into the prison cell en suits so there not that posh.

Poshest bog I’ve been in is at Claridges. Took my (now) wife there for afternoon tea.
