Whey no, they're just after confusing passengers.

Hide the A bit, make it as small as you can and cause endless confusion when Doris thinks she's getting the 2 home.
The laughs they'll have back in control, when they review the CCTV footage of bewildered passengers faces as the bus they thought was the right one - takes a left hand turning or goes straight on over the roundabout...
"Boss! Boss! We've got another one! Come and have a look at this! She's kicking off with the driver cos he took the wrong turn! Except it hasn't! It's that small A again. It gets them every time!"

"Good lad. This was a brilliant idea, her face was a right picture. Send it in to Harry Hill at You've Been Framed, we must be due another £250. Don't send in the footage of that disabled lad who got confused and upset though, we won't get as many likes on social media for that one"
