这衰落也可以视为城市结构变化的缩影。当客源被北上消费、澳门分流等改变后，传统夜总会不得不“放低身段”，与过去“动辄几万”的豪气形成鲜明对比。夜总会不再是身份的象征，而是要靠价格、促销和更直接的竞争去维持生存。这种变化的背后是一种做生意方式的改变。以前靠人情与熟面孔维系的夜晚，如今必须被写进报表、成本与风险模型里。过去夜总会之所以重要，是因为它承载了灰度；而当城市管理越来越强调透明、可监管、可度量，灰度空间必然收缩。，更多细节参见体育直播

Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.
