@fiona_mcg they’re very good, and bring humour to a simple No Entry sign. My only observation is they don’t have to be ostensibly “Scottish”,  with references to whisky and bagpipes.
What about Stay Out:
Musicians on the fiddle
Cashier cooking books
Wheeltappers and shunters only
Train driver eye testing area
On-board brewery
etc.
They could even run a competition for humorous suggestions.
I just thought that I’d swing back to this as I have been dealing with 2FA configuration for some clients - in the Microsoft settings the team have a choice of 4 things:
Call to phone
Text message to phone
Notification through mobile app
Verification code from mobile app or hardware token
By default “Call to phone” is the only one unchecked.
“The reason most public transportation is seen as ‘losing’ money is precisely because it charges for trips. If you don't charge fares, suddenly it can't ‘lose’ money. It just costs money, the same as the roads.”
This random comment has given me my new favourite argument for removing fares from public transit.
I can tolerate algebra, maybe even a little calculus.
But geometry is where I draw the line.
