I put my Caffè Nero loyalty card in the same pocket as my phone (which runs the Facebook app).

I have no way of proving this but I'm pretty sure they used my camera to read the card because the next thing I knew I was seeing ads for Starbucks (a competing coffee chain). I have never said Starbucks out loud and suddenly I am seeing ads.

Highly unlikely. More likely they're using location tracking or a shared data source to know that you like that specific coffee place.

I don't buy it. There was nothing else in that pocket.

Your pocket is irrelevant. Location tracking and shared marketing databases have nothing to do with what was in your pocket.

So you think it was my pants?

"Location tracking and shared marketing databases"

Neato. Well dude you got your answer, take it or leave it. I understand acting dumb and trolling is fun too though.
