Lay My Hat

Just received from a gmail address via OD:

"please send best rates,or if not available on these dates, then suggest similar property around this area"

Rest assured LMH's, I didn't suggest any alternative properties!

Reply:

Sorry not available. Best rates as listed. Alternatives - none available on Mars at present!

Ok it's a rather rude enquiry but how does this help people identify a scam? What was the scam?
