*On the issue regarding change:* You should always ensure you receive your change before you disembark. If the conductor doesn’t have change, it’s better to hold on to your money until you reach your destination, and then sort out the change together. These conductors often use the tactic of delaying giving you your change so that if you forget to ask for it, they benefit. That’s why, when you give them a large note, you’ll notice they pretend to be calm or indifferent, as though you haven’t paid them. You actually have to press them persistently to get your change. - Crimestop administration
