The context of the following conversation is Remy had just finished preparing soup for dinner when several friends showed up unannounced. Remy prepared several more bowls of soup.:
Remy says Clearly my friends must think I'm some sort of catering service..
The friend responds They were by the neighbourhood and stopped by unannounced?.
Remy responds Quite literally, their excuse was that they wanted to try my soup I'd been bragging about..
The friend responds Serves you right for bragging in my opinion..
