They were nothing but helpful and polite , such a nice surprise . I ' m going back today to place product and do finishing touches . I 'll be back next week - hopefully with stories ! Have a great weekend !

Question: What is the reason I was surprised by them being helpful and polite ?
Answer: They were playing a trick to surprise me .They were being nice just to trick or surprise me into thinking they were nice .They were playing a role , like in a play .It is expected that when someone helps or works they will be withdrawn or unhelpful .
