How would you interpret this sentence?
Artie proposed breakfast at the Swiss Kitchen, one of his haunts. It seemed to be a tourist place, they had a giant sign out front with a boy in lederhosen (Food Worth Yodeling About!) and waitresses dressed as milkmaids. Artie, in his ancient cuffed trousers and faint old-man smell, was unembarrassed by any of it.
“What makes it Swiss food?” I asked, studying the menu.
“A lot of grease. Bratwurst, only here they are going to call it sausage. German food with a strict doctrine of neutrality.”
With Artie, irony carries the mailbag right to the door of nonchalance. Nothing seems to excite him. Short of a revelation that one has worked for Lev Trotsky.
