A professional writer has many sample orders, you may ask any order in any discipline, be specific, you can ask nursing order, art etc.
True. Makes perfect sense in principle.
Give him 10 minutes to send you one. If the writer tell you to wait for more time, run away
The only problem with that is those of us who do this fulltime are often working on rush deadlines when you happen to email and we can't necessarily drop everything to respond to every new inquiry email in 10 minutes. I usually make some changes to any samples I provide (such as deleting some pages and references) so it can't easily be reused. Now that there seem to be some "writers" posing as customers here trying to get free work from real writers for orders they've taken on for their "clients," that's even more necessary. If a new potential client insists on getting a sample immediately, I'll do it as long as it doesn't jeopardize another deadline, but I'd find it somewhat annoying and you'd be starting off our relationship as a demanding client. Generally, the easier clients make things (starting with how much they put me through to earn enough trust for a simple 2-pg paper to start with), the more I try to reciprocate on my end of things. The opposite is also true: the more demanding clients are, the less I may give them the benefit of the doubt on things like accommodating very inconvenient deadlines or on future price quotes. Generally, the easier you make my life, the more I try to reciprocate.
