There can be nothing more galling for a manager than to hear his counterpart admit they got away with one.
Birmingham's wait for a first win of the season goes on, much to the frustration of coach Garry Monk and to the relief of rival Darren Moore.
The harsh reality for Monk is that his scoring man of the match Jota also missed the penalty which would have broken the duck.
It proved to be costly, as Matt Phillips made it four goals for the season and a point apiece.
'I'm sitting here with that feeling of possibly not asking much more from the players,' Monk said. 'It's small margins and we are on the wrong side of those at the moment.'
Goalkeeper Sam Johnstone's penalty save to deny Jota a second goal in as many minutes was described by Moore as 'game-defining' after his defender Kyle Bartley needlessly handled.
'Sam pulled off a fantastic save and it allowed us to stay in the game. I'm pleased for Sam, that's why he is at the football club,' Moore said.
'I thought we gave the ball away needlessly, that was so frustrating but we didn't lost and that was important. Birmingham showed great discipline.'

Birmingham's run is the worst start to a season since 1978 and this was yet another example of a decent performance with no-one available to provide a cutting edge.
Jota weaves pretty patterns and showed he was deadly from point-blank range when he scored the first after Gary Gardner's cross was headed back across the goalmouth by Lukas Jutkiewicz. A couple of minutes later and Jota's head was in his hands after being foiled from the penalty spot.
'In football, sometimes you shoot every day and score and sometimes the goals don't come. We need to keep working and they will come,' Jota said.
'I missed the penalty but I kept working. I thought we could win and we deserve a little more but they are a good team with good players.'
It was a miss to regret as the visitors put themselves back into contention thanks to Phillips, who took advantage of a mistake by Kristian Pedersen and beat Lee Camp for the equaliser.
Adams then had a glorious opportunity to give the home side a half-time lead. The swivel was neat, the shot over the bar horrendously overhit. Jota also sprayed one into the stratosphere.
It set the scene for the second half, in which the home side made most of the running but West Brom could have nicked another goal on the break too. Dwight Gayle hit woodwork.
In the end, it came down to that little bit of quality. Monk knows he has work to do.
