As a former dishwasher that cleaned thousands of dishes a night the last thing I want is thousands of metal straws I have to shove a Lil brush in. Also theft, we had Lil metal ramekins at one place that lasted about 2 months before most were stolen or thrown away by lazy servers who just dumped whatever was left on the plate into the trash including the ramekins so I garuntee metal straws would not last in the restaurant industry. If you can’t deal with the disposable straws bring your own straw, or learn to drink out a cup like a big kid.
