Sounds like a seasonal thing. I guess with autumn coming on you will soon be unable to see the road surface with all the leaves etc. Maybe take an extra for a few weeks?
I carry one new tube and an old school repair kit. However I have a new tube in my locker at work plus one at home.
I would ask how much of a problem would it be for you if your bike became unusable due to punctures. Can you push it home easily or ring for help etc?

No, not really. Sods law dictates that incidents occur at about the middway point, which would mean an 8 mile walk either way which would be frustrating.
I've taken to carrying a few quid with my phone, and the plan is to call a cab if I have a major problem, but I obviously wouldn't want to do that just in the event of a couple of punctures.
Great idea to keep a spare tube at work, I don't know why I didn't think of that
Mind you, I'm going to carry two anyway, I'll just have to get a larger saddle bag (or an alternative) for next Summer when I'll then need both water bottles.
