When people have problems using apps, alternatives are often available

Perhaps this is why, e.g., venues that "require" apps still have ticket printing machines and still print tickets when there are problems with using the apps

The situation is not so "cut and dried" that no one ever attends an event at these venues using printed tickets instead of displaying the ticket on the phones they bring to the event

There are alternatives to apps that are sometimes used, e.g., when customers have problems, even when businesses try to "require" apps

As such, businesses do not always succeed in collecting the same amount of data from every customer

This is not to say customers who try to avoid unnecessary data collection always succeed, either

Generally, trying is a prequisite to succeeding

If most customers do not try it does not mean no customer succeeds. There are some who do, at least some of the time
