+Event gateway immediately interrupts all catching events when any single one occurs.
+For more versatile logic consider the combination of parallel gateway and terminating event.

-===== ✔ How to =====
-Let's assume that we need to obtain payment from the client, watch the deadline and talk with the customer in case of delay. Use the following steps:
-  - Surround the "Obtain payment" task with subprocess.
-  - Start the subprocess with the parallel gateway followed by two branches, "working" and "control".
-  - Put the "Obtain payment" to the working branch.
-  - Put the timer to the control branch.
-  - End both the working and control branch with terminate events.

 ===== Notes =====
-Put extra comments here (this section is optional)
+Mind the difference between the diagrams below: while "to do" process waits for the message all the time till the end, "no to do" process interrupts when the timer triggers. If the message arrives while we are clarifying delay with the client, it won't be caught and the process will hang after returning to the event gateway.
