Maybe I am confused, but how is being warned that a company may take your money and run be a "shame"?? You would not have saved a pence. You would have lost everything you paid, then have to buy another ticket again.
I read the comment by
peggm01 as a reference to the possibility that the fares might not be valid as being a shame. I did not read that poster's comment as referring to being warned as being a shame.
