How hard is it to estimate?

I have been waiting for over 30 minutes in the queue, your host could not ESTIMATE how long it will take for the 3 consultants to assist the 7 people ahead of me, talk about caring about who walks in your doors.

Please help her with the below definition: “roughly calculate, approximate, make an estimate of, guess, evaluate, judge, gauge, reckon, rate, appraise, form an opinion of, form an impression of, get the measure of, determine”

I did not ask her to give me an exact time.

Life is about making decisions like I chose to bank with ABSA, I should be able to decide whether I waste my life waiting in your banking hall or not!
