Watch Those S's, Please

On my way home from work tonight, I overheard two people talking. Their conversation went:

Lady 1: Kaya nga every minute count.
(That's why every minute count.)

Lady 2: Sinabi mo. Every seconds count talaga!
(You said it! Every seconds really count!)

By omitting an S on "count," Lady 1 violated the subject-verb agreement. The subject is singular, therefore the verb takes on the plural form. She should have said: "... every minute counts."

By putting an S to "seconds" and not ending "count" with S, Lady 2 violated two rules:

(1) "every" should be followed by a singular noun
(2) subject-verb agreement

She should have said, "... every second really count!"
