How to Steal Coffee

I'm writing this in the Foster City Noah's Bagels, and I'm pretty sure I just saw someone steal coffee. Here are the steps to repeat:
1. Enter store, go to coffee station (which is not behind the counter)
2. Fill own travel cup that you brought in.
3. Go to the bathroom. This ensures that any employees that noticed you have now forgot about you.
4. Leave store when done in the bathroom.
