I didn't know what a summer cocktail was, so I looked up a video of someone drinking one. The first one I found was a guy making four different kinds. He drinks them with no straw. But maybe that's weird. Maybe there's something special about a summer cocktail that just totally requires a straw, except for this one weird guy. Maybe I've had a summer cocktail in my life, I don't know, but it would certainly account for less than one in a thousand drinks I've had.
So anyway, I'm not really opposed to straws. If you need one for your fancy drink, or your designer mustache, go ahead. But also most straw usage seems unnecessary to me. Pulling out these edge cases seems like what-about-ism.
