I went and got a blow dry because I'm busy and I wanted 1) quick 2) blow dry instead of straighteners 3) to relax.
I will admit that my hair is a handful. It's very curly and it is long. But most hairdressers will do a really nice curly blow in 35-45 minutes.
I was there for over an hour while my hairdresser huffed and puffed and complained to the customer who was supposed to be after me about it. It needed to be topped up with straighteners (not even ghds or another such brand) and the ends were STILL left looking a mess, which he tried to cover with a sticky 'argan oil'. Hair still looks like a witches wig.
The owner seemed really lovely and the girl who washed my hair did an excellent job. But the blow dry itself was an uncomfortable experience with a bad result.
