You would never show up to a date with gnarly fingernails, unruly hair, body odor, and a ripped T-shirt. Treat this date like you would any other. Take a shower, put on deodorant, and groom yourself. You don’t have to dress fancy, but you should look presentable.  For example, a clean pair of jeans and a T-shirt are appropriate for most casual dates. If you go somewhere nice, such as a fancy restaurant, adjust your outfit to match what you expect others to wear. All you have to do is put your best foot forward. Professional escorts won’t make fun of you and appreciate when customers follow basic social conventions like proper hygiene. Most escorts cannot accept a bank or credit card. Go to an ATM ahead of time to withdraw the payment you and the escort agreed upon. Put it in an accessible location, such as on a table, when you meet up. The escort will take time to count the money and verify its authenticity. Don’t be offended by this. They have to protect themselves from customers who try to scam them. Call the escort or the agency right away. As long as you explain your reasoning politely and apologize, they will understand. If the escort already went to meet you, remember that they invested time and money preparing and traveling. Consider giving them a tip for the trouble. Avoid stiffing them on the bill. You wouldn’t like being treated that way at work. If you cancel at the last minute, pay for at least the first half hour and travel expenses. If an agency sends the wrong escort or the escort isn’t what their ad promised, you should not go on a date. Hold the escort or their agency accountable for the mistake. You do not need to pay for the service. If the escort or their agency pressures you, refuse and walk away.  The escort service should be what you agreed to on the phone. Never feel pressured to accept a service you don’t want. Keep in mind that if you decide to go through with the date, you have to pay for it even if it wasn’t what you originally wanted.

TL;DR in Indonesian:
Bersihkan diri dan berdandanlah sebelum kencan. Tinggalkan uang di dalam sebuah amplop putih di atas meja. Batalkan kencan jika Anda berubah pikiran. Jangan berkencan jika perjanjiannya tidak sesuai kemauan.
