Top Dasher Rewards

Freedom and order Priority?
Not having to schedule to dash can be a huge advantage. Running late? No problem. This especially works well if you multi-app or have a chaotic schedule. Doing jobs for multiple different platforms can cause your dash to run out of time when pausing. When you have TopDasher you can simply get right back on the app not worrying about scheduling
Another benifit is being prioritized order's when it's slow. This can become very useful especially when you are dashing during slow hours. (Early morning/Mid afternoon)
