Decent app but flawed tip calculator – Grubhub: Food Delivery Review

App works great but the tip calculates on the grand total which includes fees and taxes. Sorry but I don’t believe in tipping fees and taxes. I have to adjust the tip based on the subtotal but doing so makes me look like a cheapskate since the percentage shown is lower because of how they calculate by the grand total.
