Just reviewing my receipt for food that was $46.80. I included the 15% driver's tip only to realize Grubhub adds that on the total that includes their service and delivery fee. My total bill was $63.18. I should have paid closer attention. The amount doesn't break the bank for me, but I think about others in a tighter budget and how many of us are pinched a couple dollars here and there. And does the driver really get the $8.24 I added as his gratuity? I just don't think it's good practice for them to do this.
