Petrol companies' price signs.   For example the price for Unleaded 91 is shown as 240.9 instead of placing the decimal point where it should be 2.409 All the petrol companies do this & it's ridiculous.  They only do this so as to create a false impression of competition when they change the 3rd decimal place.

 

Does this annoy you?

 

Its sold in cents per liter. Probably made sense when it was 60c/l or something crazy cheap back when it was all sorted out. Its obvious what it means and the problem I have with the signs is they only list the cheap stuff and the tractor fuel on the signs, not the good stuff and in many cases not what sort of good stuff they sell at the station.
