I hear you. I always get them to put the receipt in the bag but often I don't even want the receipt (just more stuff to throw into my garbage). So I follow your logic about how you're supposed to identify your stuff.
In the Lost and Founds, all you have to do is identify whatever it is you lost - Sir, it's a purple umbrella with yellow flowers - and badda bing, they hand it over to you.
You're right - the police, as well as everyone else, are obsessed with ID'ing everything.
I telephoned the phone company to ASK A GENERAL QUESTION and first I had to choose the correct department I wanted (that took about 5 separate questions and numbers to punch), then I had to enter my phone number (from the same phone I was calling on - surely they could have some kind of call display for that), then I finally got a person who asked for my phone number (why don't they already know that since i just punched it in??), as well as my complete address, my last statement amount, and my mother's maiden name. I kept telling him I just wanted to ask a general question
, but they have to follow the rules because, as we all know, 'this call may be recorded for blah blah blah purposes'... it's getting ridiculous.
Wonder what Ray Bradbury would have thought of all that. He hated machines.
Sorry for the digression.
