Casting a hairy eyeball!

The West End is transforming into a Phillip K. Dick story every day.

I know that the operators of digital signage will often decide which advertisement to show you, according to the demographic of commuters walking through. They track your smart phone and find out your, age, gender and marketing preferences.

This only works if you pay attention however :-D :-D :-D

Very tired and hungry after this. I didn't spot any food advertising (unless it was subliminal).
