To Tip Or Not To Tip?

Well according to Larry Fox, tip and make sure you tip well where it's due!  His blog, talks about what is considered a reasonable tip and what delivery men/women and waitors/waitresses have to go through to get your goodies to you. The funniest part is him putting companies on blast on his blog! 
His reason for starting the blog: "just got tired of all these big companies, these TV shows and movie sets giving us two or three dollar tips on a $90 order". 
Here's an example of bad tip that he posted on his blog:

Caption read: "Have a nice day asshole."

Tell em why you mad! Ughhh that's just disgusting! I instantly took a look at his blog and had a good laugh because I personally know some companies that will order large amounts, be picky on top of it and not want to tip.  Or better yet, place an order for ONE small soup at a company that is literally around the corner and get mad when there is a minimum delivery order of say $10.  Get your lazy butt up and get your own soup!  Lol.
On his blog he also makes a point to name all the reasons why they deserve good tips ie they are putting their lives on the line biking it through traffic on a crazy rainy day.  You don't want to leave your office/house on a day like that but you definitely expect them to do it because that's their job.
Anywho check his blog out, I think it's very interesting.
