The hindrance of the career of Arnold Rimmer...
Gazpacho soup (also known as gaspacho and gaspatcho), is a tomato and vegetable-based broth or liquid-foodstuff originating in the Spanish region of Earth, the homeworld of humans.
By the time the JMC mining ship Red Dwarf went out on its last voyage, gazpacho soup was considered formal cuisine amongst the officers of the spaceships of the Space Corps. The soup was also a favorite of Red Dwarf captain Frank Hollister.
Captain Hollister once invited Arnold Rimmer, the Second Technician in charge of Z Shift, to such a dinner. Rimmer jumped at the chance as an opportunity to get a promotion in the field, since he had failed his astro-navigation exams 14 times. Rimmer however was unaware that Gazpacho is meant to be served cold, and loudly complained to the kitchen staff about it being cold, ordering it sent back to be reheated. With the captain, all the officers and the chef laughing, Rimmer thought that they were laughing at the chef, but they were actually laughing at Rimmer.
An embarrassed, shamed and horrified Rimmer believed that this event caused him to not receive a promotion, hindering his career and holding him back as a failure. When the radiation leak that killed the crew happened (actually caused by Rimmer's ineptitude), Rimmer's lasts words were "gazpacho soup", which Dave Lister watches as a recording.
Rimmer's clone hologram mocks the primary hologram Rimmer about the incident, which the primary Rimmer says is the most hurtful thing he could have said. Under the belief that he is about to be deleted as a hologram, Rimmer tells Lister about it. Lister deletes the clone and tells the primary Rimmer that he won't mock him about it, saying "souper" instead of "super". (Me²)
