Sorry to bump an old thread, but this question came up on the amex subreddit and I thought FT had already effectively answered this.

I seem to remember in one of the location-specific lounge threads that the job postings were advertised as "non-tipping bartender". I recall someone posted a link to the job posting in either the LAX or DEN thread but I can't seem to track it down now. Can anyone confirm that these are paid as non-tipping positions?

To stir this pot for the billionth time, I honestly think "how these bartenders are paid" is the deciding factor. My understanding is that they're paid at a higher hourly rate and that they're not expected to make up any shortfall in tips. That bizarre custom is the practical reason why tipping exists in other bars and restaurants, but it is seemingly not present in the lounge. Add to the fact that we pay a premium for access and I am not thrilled about the prospect of getting nickel and dimed just because of "custom".

I will also join the chorus of others in this thread of people who simply hate carrying cash. This is a credit card sub-forum, of all places to find allies it should be here! Provided an alternative exists, I go so far as to avoid cash-only businesses in my day-to-day life. Apart from the casino, I can't even tell you the last time I handled cash. That said, I especially hate carrying cash while traveling. One more thing to keep in my pockets and one more thing to keep track of. Still, I will grudgingly take some out because inevitably I will be plopped into some situation where I am expected to tip or to otherwise forgo some "free" service (either at the lounge or hotel).

With all of the above taken into consideration, I only tip at the Centurion Lounge for exceptional service which, thankfully, I receive quite often. If a bartender offers good conversation or whips up something special off-menu then that's all I am looking for. However, if I am just ordering a beer or even one of the menu cocktails then I am not immediately inclined to tip. I find that, provided they aren't slammed, a lot of the bartenders are really happy to engage with CL patrons. That interaction adds a lot to the experience.
