On the episode where cloaked aliens were doing medical experiments on the crew, wait for the part where 7 of 9 go into the turbolift and says "Deck 5" after she says it the alien injects her with a probe. When the turbolift doors open she gets out and walks to the Mess Hall to pour a cup of coffee. How can she be in the Mess Hall if she is on Deck 5. The Mess Hall is on Deck 2 right below the bridge.
