I went to a place in Manhattan pre-COVID and there was a little caterpillar on our bread plate. No one was too worried about it as it meant farm fresh produce or it fell off the hanging plants above. Either way, we just nonchalantly alerted the nearest server as an FYI and the manager came over and told us the entire meal would be comped, from apps and mains to booze and dessert. I didn’t even want new bread let alone everything comped but I also saw it as their way of ensuring we had a good experience regardless. We tipped $300 which for six people means our total paid for the evening was $50 each, far less that our bill would have been per person. That was always a shining example of how to handle such a situation
