Panda Express

We had lunch… my bad I left my backpack inside so we went back and my husband went inside to ask for my bag. He suddenly came to me and told me that they didnt have and they didnt see it! So I rushed inside and search where I left it while my husband search in the toilet! It was not there so I checked the bin! I asked the crew if they really didnt find anything then she looked inside their small office with other crews and she asked me what color is it so I told her then she looked again inside d small office and she asked me what brand is it and told her… She then looked again in d small office and suddenly went to that small office with other crews and she took my bag and gave it to me! I should have thank her but my question is why did they deny it from the start and made me be so worried and nervous and search even in d bin when its clearly there in their office?
