International Visits
As far as food is concerned, things get a little trick when he goes on overseas visits. For many reasons, it is a bit impractical for a personal chef to both travel with the president, and to have access to everything that is necessary for meal preparation. For these reasons, the president’s traditional food screening process is slightly modified. Chances are that the president may consume some local delights. Therefore, this is the one context in which food tasting may have to be done by the Secret Service.
Anonymous Letter Writing
Even with the advent of computers, many people who have ill-will towards the president opt for writing a traditional letter with pen and paper. In any other context, it may be impossible to ascertain who wrote a given letter. This is even more so if the writer’s handwriting has no distinctive indicators. Writing a letter to the president, however, is a different case entirely as the Secret Service has a reliable method for tracing handwritten content just in case it needs to be done.
