Should I tell my boyfriend he’s a terrible tipper?

We went out to eat once and the bill was $80…he topped $5. Today we went for breakfast, the bill was $42 he tipped $3.44. Service was great both times. I usually tip 25% or greater if the service was good, so it pains me to see him tip this way. Should I bother telling him even if I’m not the one paying?
