If you are letting a TAAATS ATC know you are coming 5 miles before the boundary and you don't have a plan in the system, it's unlikely you'll get a clearance without some sort of delay.
It takes time to put your plan in the system, especially if the ATC is a bloke with fat fingers. If the ATC has higher priorities, i.e. Processing medical traffic, vectoring, sequencing or separating, like it or not, you are at the bottom of the queue.
How hard is it for you to put a plan in? If I can do it on an iPad in the cockpit anybody can. A little less whining, a little more self education will make both our jobs easier
