Feel free to pop, but please entertain if happiness below 90% (or pop mode off).

Favors returned (thanks to the feed), no need to flood my wall.

I RTF according to the specific instructions in your city page message. In the absence of a message, favors returned as offered, i.e. entertainment for entertainment, pop for pop, unless:

1) pop mode off = entertainment. If pop mode off and happiness at 100% (then sorry for not RTF)
2) happiness above 96% = pop
3) happiness below 21% = ent
