Hopefully, you'll never be in a robbery situation. Speak with your supervisor or your parents. Don't try and handle it yourself - it might escalate to unnecessary violence. Accidents involving heavy industrial equipment and machinery often involve death as well. If you're hot and sweaty, take water breaks.
Overexertion combined with heat and fatigue can quickly cause heat stroke which can cause death.
If you've had a long day - got up at 6 AM, attended school all day, then worked after school until late at night, contrary to what you might believe, both your mental senses and your motor skills could be impaired due to fatigue, so drive safely. Again, you are not immortal. If you have no choice but to work at night, don't leave work unescorted or unobserved. Have a co-worker walk with you through those dark parking lots and garages or at least watch you until you're safely back inside your car and on your way home. All rights reserved world wide.
