call and seem rude? Or do you end up late for the next one? That's why I go back to when was his previous call and was there enough buffer built in. You shouldn't have the same person calling people with back to back time slots as that's just cutting it too close. But I also have no idea how many people they have doing this or what kind of resource allocation they have available. Ideally if the employee is tied up for whatever reason there should be someone else that can make the call. I imagine the employees have the ability to reopen the selection period and so in that case him calling after the allotted time wasn't a big deal... but the end user has no way to know that and is drilled that he has to make a selection during this time period.
