How do you guys handle day game? Most of the routines and information I've learned seem like they only work for night with randomness. How would you handle initiating at the mall, store etc...? Is it much different?

It is about the same, you just have to keep in mind that girls aren't prepared for guys to hit on them in these situations and their bitch shield might be harder to brake.
Look at some of the great openers at this forum and you will see that some of them work great in day to day situations. One that works great in shopping malls, (I found this on the forum can't remember who wrote it) is "Do I look gay?" or you could make it less embarrasing and just ask "what do you think about my outfit?" you can ask her for shopping advice and if you play it right she will go with you in stores pointing out clothes for you, end with a lunch at the food court and number close. You just created a mini date. good luck!

It is a lot different. In day game you don't have to compete with as much distraction or competition. Also in a club SPAM most girls act very very fake, but when you meet them in real life they are more natural and are easier to get to know.
There are different expectations in day game, it's easier to set up a date but the girl will be more likely to see you as a potential boyfriend rather than a fling. Clubs feel like dreams, but day game is set in reality and the women will be much more aware of the repercussions of their actions. If they are stressed or in a rush, they may have little patience for you; but on the other hand without the pressure of random guys hitting on them, they will generally be more open to conversation.
The way I handle day game is by being direct with juggler's method. It is a conversationally based method that is natural enough to use in almost any situation. But basically just be sociable and talk to as many women during your day as you can. Don't be afraid to strike up conversations with strangers and broaden your social circles. Day game requires a lot less flash, so basically just open a girl and go into dhving and comfort building. Make sure to escalate and use a time constraint to number close and leave on a high note.
