When only a little can be done, doing it becomes the greatest you can do.
Making an honest mistake is acceptable. Failing to fix it is not.
Only a well-oiled machine runs smoothly.
When something needs to be improved, take your medicine - fix it.
Occasionally problems will occur. When it happens to your customers, fix the problem fast. Make it your speed and generosity that gets remembered, not the problem.
