Like stealing glasses from a pub. A shortage of glass meant that bottles and glasses were in extremely short supply. If customers kept stealing glasses a pub could possibly end up with nothing to serve beer in. What could be sadder than that?
And wartime also made people behave in ways they would never have done in peacetime. Like Mrs. Mayes in this story;
"GLASSES FROM PUBLIC-HOUSE.
Mrs. Winifred Ellen Mayes, Bird Lane, Tiptree, pleaded guilty to stealing two lager glasses, value 5s., from the King's Arms Inn, Tiptree.— Mr. F Collinge, prosecuting for the Licensed Victuallers' Association, stated that Mrs. Cox. the landlady of the King's Arms, was doing her best to conduct the house the absence of her husband, who was in the R.A.F. Defendant and some friends called at the inn Boxing Day and had drinks. After they had gone Mrs. Cox missed two lager glasses. She followed defendant and her friends, and saw Mrs. Mayes go into a gateway. Mrs. Cox went there and found the two missing glasses. Mr. Collinge added that the habit of stealing glasses from licensed houses had become very prevalent, and was a particularly mean kind of theft because in the present conditions glasses were well-nigh irreplaceable. - Supt. Phillibrown said the police had received a large number of complaints from licensed victuallers of losses of glasses. - It was stated that defendant, who was born in 1899, had held a good character. - Defendant, in written statement, said, she was undergoing hospital treatment. On the morning in question she had taken aspirin, and had some drink. She had been invited to a party that night, and had been asked to take as many glasses as she could. She intended to return the two glasses.—The Chairman said such future offences would be sharply dealt with. Defendant was fined £2."

She doesn't sound like the sort of woman who would normally steal. Presumably that's why she got off so lightly, with just a two quid fine.
That it was the Licensed Victuallers' Association prosecuting tells us something, too. Namely that the trade considered it a serious problem. I imagine they were keen on getting s few convictions for glass theft to discourage others.
The valuation of the Lager glasses surprised me: 5 shillings. Which meant the glasses were worth more than the beer inside them. At the beginning of 1942 a pint of Mild only cost 8d. Which means you could get almost four pints of it for the price of one Lager glass. Which probably explains why Mrs. Mayes knicked Lager glasses - they were much fancier than standard beer glasses.
