Common UX ant-pattern: “you have Tea and No Tea”

Posted by jpluimers on 2021/03/03

I see this pattern in a lot of user interfaces, especially on web-sites: “you have Tea and No Tea”.

For instance the example from the web site on the right: it indicates in Dutch you are getting a postal package. In the body text it says “because we send it as a letter, you do not get a tracking code” followed by a headed section containing a link to an invalid tracking code.

There was only one historic case where the condition “you have Tea and No Tea” opened doors.

Nowadays you should just put a user story on your front-end team back-log that prevents displaying a tracking code when there is none.

Maybe file an issue for the back-end team as well, to distinguish the cases where you can or cannot track shipments.

If you fix it, then an important to remember that often multiple front-ends share the same code.

In the case of the screen shot on the right, the email system showed the same issue; a strong indication either part of the code, or the design steps have been shared.

For such cases, it helps tracking back where the root of the shared design or code came started, then ensure everything stemming from that root is re-checked to ensure altered copies are inspected for the need of modification.

Er gaat iets mis met @KPNwebcare PostNL tracking codes voor prepaid SIM kaarten vanaf : de “PostNL Track & Trace code” link mist de 3S en ziet er nu uit als!/track-en-tr… waarbij op * 20 cijfers staan zonder 3S erin.

Hoe krijg ik de goede code?

Ah, een typisch geval van “you have Tea and No Tea” waarbij “Tea” de aandacht trekt, maar “No Tea” niet.

Mooie user story voor een backlog item van jullie front-end scrum teams (;

Applaus als jullie trouwens laten zien deze klassieker te kennen (;

Doe ik. Zowel site als email hebben hetzelfde probleem.
mentions Daar zitten deze twee zinnen in:

“Handig om te weten: omdat uw bestelling via post wordt verstuurd, is het niet mogelijk om deze via een Track & Trace code te volgen”


“Track & Trace code
Dit is uw persoonlijke PostNL Track & Trace code”

Met daarin dezelfde foutieve link.
