Is there a source for this? It seems kinda weird to post a story like that without evidence.
At any rate, a 5s Google of "patel hotel indian scam call site:www.reddit.com" reveals dozens of threads of people sharing essentially the same anecdote. Is that enough for you sir, or do you need something peer reviewed?
But the way he described the phenomenon made it seem pretty common, and indeed, a quick search for "patel cfo scam hotels" turns up a number of relevant results... Seems like it's a pretty well known, frequently occurring event in the hotel industry.
Not quite identical but close.
Other common scam is IT support.
