If you restrict yourself to strict RAW, Etiquette it's not that useful: it's only there to avoid problems after glitching a social test.
Not true. In fact, I would call that only the
secondary RAW usage of Ettiquette. It's much more useful for the following:
QUOTE (SR4A @ pg. 134)
When using Etiquette to ease someone’s suspicions, make an Opposed Test between the character’s Etiquette + Charisma vs. the target’s Perception + Charisma. If the character wins, each net hit reduces the level of hostility/suspicion by one step (from Enemy to Hostile, Hostile to Prejudiced, and so on). If the target wins, no reduction takes place.
Depending on your luck and skill, this can remove up to a -4 dice penalty for other Social skill rolls, or possibly even give a +2 dice bonus. Buttering up Mr. Johnson before asking for more cash is always a good idea...
This may be a house rule at our table, or something cribbed from Missions (I'm not sure off the top of my head), but Ettiquette is also useful for enhancing Contacts. At the end of a session in our game, the GM will let us know if there are Contacts we have dealt with that could potentially increase in Loyalty. A successful Ettiquette roll will increase the contacts Loyalty when dealing with them in the future.
