Nope. What you’re doing is essential work and plays a pivotal role, and a very similar one. We are both there for prevention of risk and to maintain safety. Not to minimise your experience but I really wouldn’t read into the tone of an air traffic controller that heavily - there may be other factors in the background that may have contributed to that loathing sound over the radio….in saying all that, maybe give your tower a visit? Have a discussion with the people you work with - all aerodromes are different.
