Guess your experiences differ from mine.
Let me ask you this then, how does your book(s) keep you loyal? If you’re a bookie, how do you keep your customer(s), what incentives do you offer?
My best experience is with books I’ve never had to email or call. They never contact me by phone or email besides the seldom newsletter. This might not be a very personalized relationship but I’m not looking for that, all I want is prompt payouts and no BS when you win. Other people might look for other things.
There’s been a few books I’ve thought to be great until I had a small problem, hate having to contact a book multiple times to get small issues resolved. Generally I’d say CS sucks at most books.
