THIS. We are humans, not holes to fill. Attention to detail within communication speaks volumes and tells me you value the experience I offer. "Hey" says you couldn't trouble yourself to spend a few minutes reading my website+ad copy and/or introduce yourself properly with an email. Effort gets my attention
Wild things happen all the time; don't get hung up on the why, simply use the experience as an opportunity to learn. There are so many babes in Austin! Also: if a companion offers specials so she can stack her day, that is her right and her business and only speaks to her hustle, not her value. If you book to take advantage of a discounted rate don't be surprised when other suitors share your strategy.
