We are at the laboratory where we are about to perform the experiment. We waited for the lab attendant. He spent over 30 minutes before he finally came. He was telling us that today we are going to make an analysis. We checked around the lab, we didn't see any equipment, no chemical or anything to make the analysis.
We were still waiting for about 30 minutes. Our class leader came up and asked the lab attendant, so what are we doing analysis for? He said the lab attendant said we are going to make analysis. So out of anger, the lab, our class leader said "analysis of what?" What are we analysing?
We have been here for some time and there is nothing to analyse, can we just go? He said we should hold on. We waited our time to have that session and we found out that the lab attendant wasn't serious and he didn't know his job.
He was just compromising and never knew what to do. That is why he didn't bring out any chemical or anything because he does not have any knowledge about it.
