double sink drain line config

anyone have the different configuration drawings of a double sink into one trap setup. Came across a double sink with the t in the middle draining into the trap. Each sink had its drain line meet in the middle where the T was. Usually see the trap off to one side or the other. Kind of remember seeing something that this wasn’t an ideal setup but can’t remember why. thanks

If you have a picture it would make things easier.

Scott…it sounds like you are looking at a center outlet drain as opposed to the end outlet …either is fine and normal, and which one is used is determined by where the termination point is at the wall…jim
