"Hey - come in here and watch a film! 2 for 1 on Weds if you're an orange customer."
Who in their right mind is going to respond to something like that? I noticed it was a cinema. I didn't come in. Now you've sent me a text I think I'll change my plans. Stupid.
What exactly is the point of bluetooth? Other than to send me stupid text messages when I go past a cinema or a phone shop? You can transfer files from one phone to another ... and that's it. Leave it on and you get these awful spam texts everywhere you go. Absolute nonsense.
I've switched the function off on my phone now, apparently this saves battery. But it still annoys me that there must be mobile phone signals sturting out of the shops/businesses that use this form of advertising. Can't do us any good to have the unnecessary extra radiation in our densely populated areas like that.
The only good thing about bluetooth is it's named after a Viking. Vikings are cool.
