I drink my water hot too. Especially in the winter. I do think it is an Asian thing since I am Chinese-American and my mother and sister-in-law have always drank their water this water. Something about being less of a shock to the system.
As for the multiple bags, I too have long try to deal with this problem. My daily commute consists of a .75 walk to the Metro/subway, 45 min Metro ride, followed by a bus ride and another 10 min walk. I use one stylish tote containing my wallet, cosmetics, dental hygiene stuff, headphone/iPhone, & coupons. I use a second larger lightweight tote (Scout bag http://www.scoutbags.com) to carry lunch, water, shoes, daytimer, kindle and a magazine. I am definitely loaded down and probably look like a bag lady.
