got two boys outside who say they are doing the scheme (washing cars) and they trying to get 100 customers. they come round once a month and once they got 100 then they can get business cards etc. they have 68 and the guy over the road has just had his car done by them so i said ok. they come inside to get water. fair enough as its just two lads. but u cant help worry. i guess the only reason i dont think its too suspect is that they want to come once a month so if it was a con surely they wouldnt push that...would they???
