Anyone else have people who didn't give a gift?

We had 3. One I knew about (financial situation) and it's a family member so I told them it was ok. Another, my family member told them it was ok (didn't know) and I didn't want to make a big deal about it but was mad when I found out . Then one of my husband's coworkers gave 50 dollars for 2 people. This woman brought her daughter as a guest. Another coworker 'forgot' his card. While we are going though cards we realized that we were missing one from them. We figured we would give it until we got back from the HM to see if we heard anything from them, heard nothing. So I told DH to text him when we got back and make it like we wanted to make sure we didn't loose it. He did and my husband still had to apporach him the next day because he was sleeping and didn't respond to the text. The guy said he forgot it and they realized the card was still there when they got home and he would bring the card in. Now him and his gf who attended are both out this entire week. So we still have no card. Waiting to see if he gets it next week..
