Let's restate that in the current situation - you are lost and know you need to get off the highway, but know know which exit. Your friend finally calls you back and tells you it's the exit that coming up - you've already passed half the cars waiting in line, but you slow immediately and get in line. Did you do something wrong? Very different than doing it intentionally and repeatedly.

As I said above, holding multiple tickets because you can't make up your mind is very different from using the option due to circumstances beyond your control. Not ideal, as others could be impacted, but to me being ethical doesn't mean looking out for others at all costs to yourself. There is middle ground.
