Despite his concerns about privacy (it was more that he understood Tony simply could NOT resist poking his nose where it shouldn't be rather than distrust of JARVIS) there were many conveniences JARVIS afforded the Tower in addition to security and safety. Such as ordering food for them ahead of time, taking account of their tastes and making sure it was delivered at an optimal time for consumption. JARVIS was also flexible enough to allow quirks like Hawkeye's fondness for crawling through vents and Bucky's habit of trying to jump on him from behind doors without undue alarm after he was warned ahead of time and once he saw this was more of a game to the participants.

As soon as Bucky tipped over to the side Steve was rolling up and on to his knees, made difficult with one hand still held captive by Bucky's metal one. He crouched lower in preparation to pounce but the sudden addition of blankets caught Steve off guard and he struggled with them in his hands for a split-second. A split-second that probably left him open to attack that would have been fatal in the field.
