Smoking In the Popeyes??

So today I had two gentlemen come in about 5 minutes before the lobby was closed and even though we packed them a to-go bag, they insisted on sitting down, but whatever that’s fine. However about 15 minutes go by and it’s 8:10pm and one of the dudes start smoking in the store??? Why do people still think this is okay? My manager had told them to stop and if they didn’t they’d have to leave and they did — but still? what’s y’all’s opinion on smoking indoors?
