Here's what you tell them if they raise an eyebrow about riding a bike:
-You can change a flat tire on a bike quicker than changing a car's. Meaning less likelihood of you being late.
-Your bike doesn't require fuel like a car, so you won't run out of gas on the way to work. Again, greater chance of being punctual.
-Less chance of getting a speeding ticket on your bike... see the pattern?
And walk-in freezers make for great places to cool down after arriving sweaty. I used to take my breaks in the cooler when I worked at BK.
