Among the other good comments about distraction, downtime and wealthy lifestyle, I've been using Perform as a signal to be very generous with the Perform-proficient player in terms of using the Help action in regards to ability/skill checks out of combat.
Can you help someone on an ability check involving a skill or tool you're not proficient in?
How far from you can the person you're helping be?
Does the way you're describing your action make sense for the DM to allow it to qualify as Help?
Is it possible to Help more than one character at a time?
Can you Help someone in an ongoing way or to aid a check they'll make in a minute or an hour, as opposed to before the start of your next turn?
For characters proficient in Perform, I generally like to rules these questions in their favor when it comes to Help.
I've employed the "Aid" rule a little more liberally when it comes to complementing skills. In the case of Perform and Deception, I will allow a player to roll with advantage if they are proficient in both when they are deceiving with a performance -- such as a fake fight to pretend to champion someone else's cause (and gain their favor), to create a sting operation and set a trap to catch a culprit ("accidentally leave a valuable item exposed/dropped), impersonating an important figure to deceive potential assassins or opposing political factions. For characters attempting to intimidate, I'll also allow an advantage if they have perform to "threaten by a display of physical or martial prowess" -- think kung fu movies and the posturing/katas done just before a fight.
I try to ensure that every skill/ability check as a game repercussion and have value to the story. Even for the "Entertainer" background, I require a perform skill check to determine quality of room and board. A failure results in the lowest possible accommodation and a "bad review" that increases the DC in the locality for the next perform. Likewise, a success results in a "good review", and a lower DC next time at the same inn.
In one of my adventures, the party was guiding a caravan through heavy fog (everyone was essentially blinded) and the Bard acted as a guide by singing from the front and everyone followed the music. I had the Bard role perform as a test of her endurance over the many hours of the trip. As a reward, she became known as the "The Guiding Song" and a local legend.
In my current game, there are numerous bards, several of them competing, and the perform skill check establishes if a bard has sufficient "star power" to speak with another bard. Likewise, too high a success in some cases turns into a threatening "star."
In the same game, several NPCs are deaf, so languages are not going to work. However, a Perform skill check enables sufficient pantomime to communicate (ad-hoc sign language).
