Customer ratings are such a crappy metric..

It's such bullshit. Out of our last 100 runs, one customer, apparently just for shits n giggles left us a 4 star review. It brought us from 5 to 4.95. below 4.9 you lose sapphire. Really fair. We have never delayed for any reason in our control getting the customers orders to them, usually it's either traffic or lack of an apartment number or any other reason. Someone's having a bad day and gives you a 1 star review even though you did nothing wrong, there goes your sapphire

That is far too little wiggle room. Half the time I use the self checkout at Walmart I leave a 1 star just because they can't be bothered to have 1 fucking register open so I have to do the work of a paid cashier and check myself out.

They need to be a little more lenient on this. A truly bad spark driver who is constantly fucking around will have a pretty obvious track record. A customer just arbitrarily picking a random rating can literally lose you the ability to get better JFY runs and drive your income way down. Ugh.
