As for the “Guest Shopping” order mode, this option is not compliant with all EU directives on personal data protection and consumer rights:
- the customer has no access to their personal data stored on the store's server,
- the customer cannot edit their personal data,
- the customer cannot submit a “right to be forgotten” request,
- the customer cannot return purchased products (they must convert their guest account into a standard customer account).
In addition, the “Guest Shopping” order mode is a terribly customer-unfriendly option. Customers have to laboriously fill in dozens of their personal and address details with every purchase.
So if someone uses the “Guest shopping” mode in the store, they don't need the “Cancel order” button, because one more or less crime doesn't make a difference.
