One day last year I sent out P411 requests to different 3 providers saying I was suddenly available that evening and was looking for a last minute appointment. I setup something with the first one to respond and offered my thanks to the other two. One of them was annoyed at the tactic and we had a friendly discussion about why. I decided to quit using that technique.
Since then, I send out a request (email or P411) to a single provider and then wait. Some providers respond immediately and some never respond. I’m never sure how long to wait before trying someone else.
So I’m curious what providers and hobbyist think is the proper etiquette for finding a date over email or PM. Is it wrong to send out multiple queries and take the first responder? If I should only send one at a time, how long do I wait for an answer?
