To think this Santander poster is stupid and irresponsible?

I keep seeing this big poster in Santander’s window, since it’s right beside the bus stop I use in town.

Below a large colour pic of Ant and Dec it says - in very prominent red lettering:

SCAM-OUFLAGE
‘If they can’t see you, they can’t scam you’

Then, well below that, in considerably less in-your-face lettering,

‘Or stay safe with our scam awareness events.’

Is it any wonder that naive people are duped, when posters like this are prominent on (presumably) so many high streets?
