I also agree with Tonus - I never used to feel comfortable with some forms of ministry. Street work - stopping randoms as they go about their private business - and calling on homes at clearly inappropriate times, like Sunday mornings.
My favourite part of ministry was actually having Bible discussions/studies, because you knew the person wanted to be there, and it was a chance to really dig deeper and discuss their thoughts and feelings. But opportunities for these got rarer and rarer, partly due to increased lack of interest, but also partly due to the watering down of the study materials we were supposed to use.
Over the years, the two new tools which could have substantially improved the ministry are the website and the use of public carts (trolleys, as we often call them in the UK) - but even these methods have been watered down due to over-simplification.
The cart witnessing, which many mock, but I feel could be a good method if used properly, is reduced to advice to just stand there and smile at passers-by, then direct them to the website or swap numbers with them if they show interest.
I enjoyed it at first before they changed the rules (originally, we could stand offering publications in hand, and engage people in conversation), not once the role just became a mute nodding dog routine, made worse by other witnesses spending the time standing around chatting, drinking coffee and checking their phones.
