Correct, but I am referring to the timeline.
It's like ordering pizza and they tell you within 30 minutes and within 15 minutes you are already calling to find out why the pizza hasn't been delivered. You should wait 30 minutes and if they don't deliver by then, you call to inquire what happened.
If I am the phone responder at the pizza joint, I would be aggravated if most customers called in before the approximate delivery time given, especially if I am also working on other things at the same time to get the pizzas ready. And let's say you don't call in after 15 minutes, but instead decide to go on Yelp.com asking "Why are my pizzas taking so long to be delivered?" How would other customers view your business if they see that?
It's a dumb example, but I hope you understand where I am coming from.
