If you get upset because somebody backed out of a "deal" even though nothing was exchanged you have other issues. .
Actually no. If you and another party have agreed on terms and are waiting to meet, both of you have resources tied up at that point and those resources are not available for other purposes. To that end, "something" has been exchanged and this is a recognized legal principle which is why in situations with much larger stakes remedies are often pursued. Just that here the remedies are so small as to not be worth pursuing.
It has nothing to do with "being upset." I've had the exact scenario happen to me several times. It never upset me, but it did mark for me who could not be relied upon to hold up their part of a deal.
