For example: In our Sunday service someone speaks in tongues and then tells us what was said, would this be correct?
ESV - 13 Therefore, one who speaks in a tongue should pray for the power to interpret. 14 For if I pray in a tongue, my spirit prays but my mind is unfruitful.

Just wanted to say that I have read the above Bible quotation before, but showing this does not answer the original question. I have often wondered about different aspects of speaking in tongues, also.
Tongues are a sign to unbelievers; prophecy to believers (1 Cor 14:21-22.
► Following order must be followed while speaking/interpreting tongues during a service:
✿ All speaking in tongues at once causes mockery by the unsaved whereas with prophesying the unsaved are convicted of sin (1 Cor 14:23-25.
✿ Every gift must be used to edify the church (1 Cor 14:26. Prophecies do this better (1 Cor 14:1-5, 23-25.
✿ Only one message is allowed in a church service if not interpreted (1 Cor 14:3, 27-31.
✿ Three messages in tongues are allowed in any church service if they are interpreted. (1 Cor 14:27-32.
