[請益] expire

[ambrosio (...)]

Food is risky. You can choke on a hot dog, be poisoned
by a pizza or die slowly from years of eating too much. Clearly
businesses taht sell food are suspect. And what could be more
suspicious than an outlet that sells food-- and then drives away
before its customers expire? Small wonder that so many American
cities frown on food trucks.

這是經濟學人裡的一篇文章，在講流動攤販。
請問倒數第二行的expire要怎麼解譯，我想
很久，想不通，是形容很生氣嗎? 謝謝
