Training when the gym is busiest and equipment order keeps changing

The gym near my work is packed when I can get there. My planned squat–bench–row order turns into bench–row–squat, or dumbbells instead of the machine, depending on what's free. I used to wait around to preserve the ‘correct’ sequence, which wasted half the session. For general strength and consistency, how much does exercise order really matter? I know heavy technical lifts deserve more attention, but most of my routine is fairly straightforward.
