Surfing around found myself entranced by this post over on Reddit:
Sure the design of the cup makes you feel like a child— which might be what the bar wants. Perhaps there are other designs out there that would hold up to the rigors of food service but I have yet to find one that fits the bill. Maybe one fully made of glass, with a wide straw opening?
Then of course you could use metal straws.
I have yet to see a bar actually washing the inside of them properly so your mileage as a bar person will vary depending on what the boss got for the place.
You could also use paper straws, which seem to be the preferred solution for bars everywhere.
People will complain they go soft too quickly… but that’s because you’re leaving the straw inside. You can put it on the bar on a napkin, or on a saucer if provided one.
Me? I’m all for sippy cups.
