That means without a straw. That's how I order any drink that might come with a straw. If it's an upscale place I'll say without a plastic straw because some places are using paper or organic tube plant straws or glass. About four out of five times they forget and bring a plastic straw and I gently lecture them on how they don't decompose and often end up in streams and the ocean. There is a movement to get restaurants to stop using them. We're all still doomed but it seems like a good effort to make.
