In the practical sense, I think one can perfectly well see a person typing out that quick response and then calmly making a call. They were talking same locality--not, for example, a specific shared workplace. It was a hotel in an area where someone, presumably NOT a worker in that hotel, actually RESIDED.
Then, not to put too fine a point on it, why attempt to castigate or insult that person? IMO, that is just small-minded and mean. It's something you might want to think about, rather than figuring out a response here.

Thanks for the suggestion...no really...I'll cherish it forever ...and when I mean forever I mean for 2 seconds
