Summer is coming up and I think I will get a 2nd job b/c I'll only be working a little over 20 hours with my current desk jobs.

I was thinking like bartender... bouncer... something with that PUA SPAM.

Let me know!

I definitly advise you to work in a club or restaurant, waiter seems like where you get most of the opportunities to flirt. I have been a bouncer on and off for a couple years it's also a nice spot to be in for a PUA.
I think working with tourists and foreigners can also have some potential. Guide and stuff type of work. I was trying to get that kind of job this summer but I couldn't and stuck with bouncer.

^ What he said. Bouncer is probably the best because to be one of them you're big, strong and have the responsibility of keeping the place safe which makes you incredibly DHV and alpha in the eyes of girls.

Failing that, if you have the confidence there's a few options at your disposal.

1. Glass Collector. It's a shite job but somebody has to do it, and lo and behold it has the mother of all potential. If you work in a packed nightclub picking up bottles then you will get dirty but girls will be well too hammered to care. You'll be out round every corner of the club, and people will often try to open YOU just because you're working there and they think it's cool.
2. Pizza Boarding/Sign Holding. Standing in a public area, usually handing out fliers and advertising somewhere on a signboard is often a great way to meet people. Just don't do it at a car park like I did because they won't stop around long enough for you to put the alpha on. It's also cold and dull as shit.
3. Tour Guide. This is incredibly awesome because your knowledge of the city or area you're in is DHV and you'll be interacting with people on a daily basis. However, your obligation to lead the entire group (and not just the cute Japanese tourists) will definitely keep you from isolating. You may get phone numbers, but opportunities to do so will be slim.

Ultimately though. Be a professional and get a job that's good for money. And don't be a bartender unless it's in a bar and not a nightclub. If you're bartending in a nightclub where the music is so loud you can't get a word in then you won't be able to game at all, you'll be stuck in one place and usually getting accosted by assholes who think that £3 for a double shot of vodka is a ripoff.

Bouncers and bar tending at a pub/bar are always a great two, but then again so is retail... Working in a store that sells female clothes will give you an opportunity to approach the girls indirectly as soon as they enter the store,

eg.

"Hi, are you looking for anything particular?"
"Hi, can I help you with anything?"
"Hi, how you going?"

Or my personal favourite, go upto a girl who comes into your store, and tell her straight out which piece of clothing you think would look amazing/sexy/hot on her. It demonstrates high value because you know what you want in a girl, and you're not shy to make it clear.

Best of luck!
