How should Buddhists receive generosity?

There is a lot of advice about dana and the importance of generosity and giving but is there any advice on how to receive generosity? From a western perspective it can be quite awkward to receive gifts or charity so I wondered if there is any specific Buddhist advice on how should this be done - both the actions and the appropriate mental state. The motivation for this is this you tube video where Yuttadhammo is receiving alms. I found it very striking the manner in which they are received - without any thank you or speech. This could be a cultural phenomena within Sri-Lanka or how alms are received generally - I'm not sure. However it makes me wonder in what spirit generosity should be received from a Buddhist perspective generally.
