Never really felt the need for straws myself. The adult sippy cup lids that will be the likely replacement for most uses will do the job for about the same cost and a smidgen less plastic.
not at Starbucks. linkMaking a regular lid into a sippy lid shouldn't add all that much more plastic and the amount added should be less than a straw. Sounds like Starbucks must be having their sippy lids do something more than making it possible to sip their drinks. Either that or they have horrible designers,
Starbucks:
>Bans Plastic Straws
>Still Uses Plastic Cups
Star$$$ wants people to see their drinks, but yea, a plastic cup ban would be better plastic wise than a plastic straw ban.
