Satisfaction & Dissatisfaction

This is a story about satisfaction and dissatisfaction:
On Sunday last week, I had a date with my high school friends for eating something at Sorya Supermarket upstairs.
The staff inside escalator asked me what floor I wanted to go then pushed the number of floor.
I was really satisfied with such interaction because doing so is really convenient for those who don’t know well about the way of using escalator. Moreover, it makes people understand a little bit about the use of escalator.
However, before eating, I had to convert my money into coupon, or I could not buy fried rice or soup, which makes me feel a little bit dissatisfied. Especially on weekend, there are many people visiting Sorya supermarket; therefore, I had to wait for to get coupon. Thus, it really annoyed me a little bit. Nevertheless, the staff exchanging coupon are friendly all the time to all customer.
