Friends is a well known comedy sitcom, this style of comedy is filmed in front of a live studio audience so the laughter you hear isn't tracked. With this in mind the editing style is a little different to your standard studio based film production.

First of all Characters cannot speak, or have to wait for the laughter to die down from whatever joke or pun has just been made before continuing their lines. Friends I believe for at least the first seven seasons was not only filmed by recorded live as well. This meant there would have been a director in a back room eyeing all the monitors and calling camera numbers for the operator to switch to.
We who watch the show through various technological mediums are made to feel as though we are part of the live studio audience, and with that in mind, a lot of shots are either wide or mid shots. Close up are rare because if we were sitting watching the show that's how we would see it naturally, the only way to zoom in, in real life if too move closer to the subject or the subject to you, and as that is not the case then they keep to wides and midshots.
As you can see from the scene in the coffee shop the camera is directed at who ever makes the joke then subsequently to the reaction of those around them or whoevers line is coming next. When Ross explains the sandwich situation we only get a midshot reaction shot from Joey and Chandler/Monica. Although Joey doesn't speak he is on the left side of the main character so it is natural to look in his direction, and as with Chandler and Monica, they have lines coming up and it more natural to get them in a midshot two shot than to move the camera back and also get in Rachel. This gives the audience to much to look at and might divert attention from the scene. This is why Rachel does not speak throughout the scene and is only seen in a wide/Establishing shot to the scene when Ross walks in.
The next scene is interesting because although both characters are positioned so that the audience gets a full profile of them in a two shot the camera has elected to go for an over the shoulder match on action. This is because it helps slowly build the tension. The characters are lobbying conversations back and forth, slowly at first until Ross finds out he ate his sandwich then the cuts between them get fast and faster with Ross' bubbling rage. This would not have been as effectively accomplished in a two shot where the camera would have had to have been stationary or pan from character to character.
