David taught them his trick after they changed into their uniforms and as they were fast learners, it just took them an hour to master the technique and they could do it almost as swiftly as David.
David was impressed "I knew, you make a great team so now you have to set off to your investigations for this week. You have to go directly to work instead of coming here, staring tomorrow and I need a good result by the end of the 7th day. You can't be discovered during this time and you will only collect the information."
Both of them nodded and were ready to set off when David called them "You have to be undercover so change your clothes before leaving, they are already there in your changing rooms."
