Great customer experience:
I have been working out with a Gym for the past 3 years. One day, I had not slept well and yet I woke up early in the morning to show up. I was very tired and I did not have the energy to follow the workout plan. One of the instructors asked me to go home and get some sleep so that I’d be able to get through the day. This happened a few more times and I got annoyed because I felt bad to go all the way back without getting my workout done. I started making it a point ot sleep properly so that I can get a good 1 hour workout. In the next 3 months, this started becoming a habit and my performance improved gradually. As a customer, I was happy ultimately.
While typing this I am not sure whether this was a Force or a Friction. The instructor being well aware of the client’s state is a Force and asking the client to go back is a Friction. Would love to know more thoughts here 
Poor customer experience:
I ordered food from a restaurant recently and I had forgotten to specify the dietary constraints that my friend has. I called up in the next 5 mins and the phone line was busy. I had to wait for 5 more minutes and make another call. When the call was picked up I apologised for missing to mention the specifications and asked if it is possible to customise. Instead of addressing my concerns directly, he said they can only take customisation requests if it was placed within the next 5 minutes from the time of order and I had called up only after 10 minutes. I tried to explain that the line was busy and then he started going through the call logs and said I had only called them 6 mins later and not 5 minutes. A simple explanation saying that the chef has started preparing would have saved a lot of time and energy for both of us.
