I walk home 2 miles toting heavier stuff than that. Hey, two or
three large cokes of the size you describe could easily fit in one
plastic bag. Just double it up. You should get a bunch of strong
ones and take them to work with you. Keep them in the car and use
them to carry heavy stuff. Just remember to take it back after the
delivery. And for the last time, I don't care what you do or don't
do, just be glad you get any tips at all. I've been doing what I do
for 33 years and make less money by far than you, and as good as I am
at what I do I still know that a tip is not supposed to be a mandatory
thing but rather a gesture of some sort of kindness or appreciation
from the person you're serving. And let's not forget the huge tips
you get when you least deserve them. It all balances out. You need
to listen to the Big Buddha buddy boy.
