What happens during rush hour?
- Transit gets better, it has more frequent service
- Cars get worse, backed up in traffic
- Crosswalks get less dangerous. It's hard to get hit when there are a dozen other people around you.
- Buffets taste better, because the food is replaced more often and therefore is fresher
Speed matters. A 15 minute wait might be desirable while eating at the restaurant, but it's a deal breaker when trying get takeout before a train.
Consistency matters. If the coffee unexpectedly takes 3 minutes to brew, a cafe has just failed a regular customer who expected the usual 1 minute.
As a professional (this includes not just the restaurant owner but also the civil engineer) you might feel overwhelmed by serving your customers during rush hours. If this is the case, consider offering a type of service that gets better during rush hour.
