Yup. Might as well walk into a supermarket with a bottle of vodka, and mention to the cashier 'yeah, it's my lad's 16th and he wanted something to spice things up a little - oh, actually, no, forget I said anything. Yes, this vodka is definitely for me, now I come to think of it.'... You ain't getting served, now, sunshine! No amount of protesting will allow it. Jesus that happened when I was helping carry two bottles of ale, because my old man was juggling with about half a dozen, couldn't carry any more, and were doing the bloke thing of not getting a basket. He had his ID, of course, being a man in his 50s. I was 28 at the time (and happened not to have any ID/wallet on me at the time) but because I was carrying/had touched two bottles, she wouldn't serve me, or him! So ended up leaving the shop (let's call them Besco's) empty handed.
If you mention it I'd expect a funny response, and potential phone calls or worse, a knock at the door. I'd fix it yourself. If you were nearer I'd probably be able to put you onto a guy who'd let you have screens for very little each. Surely they're dead easy to source on here?
