It is to be noted that CIA is not the Central Intelligence Agency, but the Complete Idiot-proof Assistance.
And the sub here refers to a nuclear-powered submarine capable of launching a nuclear warhead.

We all have been through this, ordering our first sandwich. And at the same time not to be completely lost over the gazillion different possibilities that can be made or look like a complete fool by just saying ‘everything’ unless if you have a really unique taste bud.
So here’s the CIA’s guide to making a sub!
I’ll start of with the basics, from ordering your bread to actually eating one.
1. The First Move
You enter the premise and greeted with warm smiles accompanied with the usual ‘Welcome!’ yell.
So yes, greet them back with an approving nod and a smile, or just say thank you.
Here, we are overwhelm by the available choices (12 or more maybe), ranging from the old school to a full vegetable onslaught plus another 3 as a hidden bonus to be unlocked after defeating the final boss on the last level.
Wait. That doesn’t make sense…
But there IS an additional sandwich(es) apart from those which are nicely pictured.
So how do you actually choose a sandwich? Unless you are a vegetarian, as it narrows down your choice to just one.
We never choose. We let our stomach do it. As cheesy as it may sound, it’s as close as choosing the colour of our future car. If you don’t notice it, each and every time you try to pick one out, you would usually order the first one that actually rings something in your mind. Or twice, if you when through the menu twice la.
Unless of course, you already have a craving for a particular sandwich, or you simply lack the financial capabilities and have to opt for the sandwich of the day.
SECRET TIP #1 Try to refrain from staring too much at the cute guy/girl behind the counter. You can do that later when you eat (unless you ordered for take-out). It disrupts your ‘stomach brain’.
2. The Next Step
Here, it’s up to personal preference. But assuming it’s your first time, it can be really daunting since before this, sandwiches only came in those Gardenia slices, a baguette or a croissant.
Now you have the ability to pick not one but FOUR (or five) type of bread!
I can’t help much here, but rule of thumb would be, do not go for any of those wholegrain type.
3. The Deep Cuts
Refrain from saying ‘everything’ here. As much as you are tempted, the choices are very basic.
What do you expect to be on a sandwich?
For starters it could be lettuce, tomatoes and onions. That’s it.
SECRET TIP #2 Make up your mind when your sandwich is being ‘meated’ (the process in which they put the beef strips/slices on the sandwich). There’s a list of possible ‘fillings’ to choose from.
4. The Final Touch
You’re nearly there!
Here too, refrain from the favoured ‘everything’.
I do not eat Thousand Island sauce with beef pepperoni.
Or Teriyaki Sauce with tuna.
Mustard and chilli go very well with hot dogs and burgers.
Thousand Island with salad.
Mayonnaise with tuna.
And the chilli sauce is specially made from imported chillies from India and Mexico.
SECRET TIP #3 Sos letak lebih sikit!
Hey presto!
You’re finally done!
Now, that wasn’t too hard, was it?
