DO: Make sure you show up on time. And by "on time," we mean "15 minutes early."
These days, you have approximately 35 different ways to tell time. You've got a watch on your wrist, a cell phone in your pocket, a navigation system in your car, and...oh, you get the point! And yet, folks are still showing up to dates at a quarter-past your date being pissed off because you're late! Yo, show up on time! And, if you're not, the very least you can do is Google "excuses for being late for a date" before you show up.
