The sign refers to column 27.
It's on column 23.
So where the f**k is this column 27?
Go to the right and you do not find any column in the parking place, you have to leave the parking place, go beyond a yellow line and then look further only to find that this is..column 21. B****r.
Oh well, retrace your steps and go to the left of column 23 and the only other column in the parking place is column 25.
Where and how would you find column 27? Traipse the streets? Remember, as a motorist you are safe ONLY as long as you remain in the parking place to read signs, make calls, use apps to pay etc. It's when you leave that you become vulnerable.
IMO, it's preposterous to expect a motorist to leave their car in potential contravention in order to search for a clue which isn't even on the parking place.
