1. Good hygiene! Please brush your teeth, instead of just chewing gum. Keep in mind that the better you smell, the more confident you feel about yourself.
2. Ladies are of course free to ask men to dance, although it is discouraged in Buenos Aires. Being asked is a big compliment for the men in North America.
3. Cool down. If you are sweaty, take a break for a dance or two to cool yourself down. Dancing is not a workout...
4. If you are asked to dance, please accept. If you are tired, you can politely decline the offer, but please don't accept any other offers until the music ends. This is true even if the man looks like Ricky Martin.
5. Try not to dance with the same person many dances in a row (unless this is clearly consensual).
6. Unless s/he is hurting you, try not to terminate the dance at the middle of the music. It is not worth hurting people's feelings.
7. Please do not correct others. The socials and classes are not at all the same. Moreover, you are not an instructor.
8. When the music ends, stop dancing and applaud the band.
9. Say thank you for the dance.
10. Leave street shoes at the coat check. Most dancers in North America change their shoes to a clean pair of (dance) shoes. It is not pleasant for others to see your shoes under the table. Also, carrying our shoes in a 'Safeway bag' does not appear very elegant.
11. Buy drinks at Dance venues. Keeping a good relationship is very important for the dance community. However, none of us want any drunk drivers. Drink responsibly. If you don't drink alchol, please purchase a soft drink, food or at least tip the workers. Bars have a lot of overhead.
