This is our walkthrough for The Tech Entrepreneur Payphone Hit in GTA Online, a mission from The Contract DLC, covering all three assassination bonus variants. Each variant involves a taxi, and the guide aims to help you effectively eliminate the target and earn the maximum payout.
In this mission, you need to assassinate a target who is drunk and, no matter the variant, is always coming out of a hotel.

All the mission variants require the use of a taxi. You can always find the taxi in the marked location below. This is where the game also sources the taxi for you.

Variant 1: Gas Station Explosion

In the first variant, you need to pick up the target in a taxi and take them out with a gas station explosion.

Once you've got the taxi, go and pick up the target from their hotel.

When they're in, go to any one of the gas stations around the city. The following are the most common and easiest to find in the city. You can always go to the one you know of.
