Lalamove for just a few things?

Hi everyone. Quick question. Got two TVs, and an office chair to move, 15mins drive ish.

I understand I can't ride in the back to "jaga" the items. I have no car, so I have to take a grab to the location for dropoff, but what happens if I can't get a grab and I arrive like 10-15mins later than when the lalamove driver gets there?

Surely they can't just chuck my stuff in a corner somewhere? Or is there some waiting fee applied?

Thanks!
