What really is the point...?

Got Radio 2 on at the moment.... there is some 'love song' request show currently running...
Why the hell would you send a request to somebody you have never met to tell your loved one that you love them on the wireless...?
What percentage of recipients ever hear the request...? "I had a request played for you on the radio but you were on the bog"...

And why does the DJ say "this is just for you..." when she has read about ten requests out...?
And what if you make a request, the recipient actually hears it but the DJ has picked a song that he/she loathes...?
