I'm a relatively new player and I went on my very first Arcade run with a group. One of the players didn't speak, but instead only spammed the same message near the elevators, suggesting someone pick up his tab. He would not trade for crowns or say anything else except his set "Please pay my elevator tab mext to my name" suggestion. I waited for a long time for him to at least give in and instead I grew impatient and decided to give in.
For a first run, that's a bad impression and would rather players NOT be able to descend into the Clockworks if they don't have the Energy for it and essentially force other players into paying a tab just because they've already spent their Energy. If it persists, I'm just going to quit and that'll be that. Perhaps by letting individuals up and leaving those with no Energy? It's just not worth the crowns or my time to just give Energy (to people who may very well have enough Energy and are just not paying!)
If the circle and arrow is red, they have less than 10 energy total.
If it is yellow, they have at least 10 energy total.
