Another split shift

I was still pretty exhausted from yesterday this morning, but I had to get up early in order to get ready for work. I had another split shift today. In the morning, I was working from 10:30 to 2 PM. We had a lot of restock to do and since there was a cruise ship, we also had a lot of customers this morning. Thus, my first shift went by very quickly.
I spent my 3.5 hour break at home, where I had some snacks for lunch and spend most of the time just relaxing. By the time I had to leave for work again, I was feeling even more exhausted than this morning. Thus, I drank some coke, which actually made me feel a lot more awake and enthusiastic.
Like usually, I had planned to take an earlier bus to work. I was at the bus stop on time and the bus was a little late, which wasn't too bad. However, when the bus finally arrived, it just displayed the message 'Sorry, we're full' and drove past my stop. I was very annoyed by that since I was worried about being late for work now even though I left the house early. Luckily, there was another bus 5 minutes later and this way, I was still on time.
The first part of my second shift today was quite busy. However, it got really quite around 8 PM, so that I had the chance to clean the toy area a little.
We had a lot of US customers today who paid with USD. By now, I had figured out how to handle those transactions best: If the customer paid in USD and I told him that he would get Canadian change beforehand, the customer would often not be very happy about that. However, if the customer paid by USD and gave me almost the exact amount, I would just accept the money and give the Canadian change to the customer with the words 'And some Canadian coins back for you as a souvenir.'  That way, the American customers would actually be happy about their change and thank me for it. It seemed funny to me how rephrasing a sentence could change the reaction of the customer. Unfortunately, this approach would only work if the customer paid almost the exact amount. Otherwise, I would have to inform him about the change since it would be quite a lot of Canadian money.
By the time I was done with my shift at 10 PM, I was a lot more energetic than I was at the beginning of my shift and I easily could have kept working a little bit. Nevertheless, I was happy to get home as I was very hungry. Consequently, I had a late night snack just when I got home around 10:30 PM.
