From my reading, they’re saying you’re still welcome in Starbucks with your guns. I think they mean that guns aren’t allowed in Starbucks alone, but if they happen to be carried by a customer that’s okay. :-)
If anyone complains about you standing there and placing an order and minding your business, they are going to ask you to leave. How do you read that as “saying you’re still welcome in Starbucks with your guns”?????
