Depends.
Case #1 if I overhear them talking erroneously about something, where something is or how to go about something...then I step in and give the correct information. (This happens quite often, esp guests who only stop overnight and think they have "been here" and have missed it entirely! But still give others at the table their so-called wisdom on the subject, incorrectly)
Case #2 if they are one couple on a romantic getaway, I am there if they need anything (tell them I cut the strawberries in the shapes of hearts just for them...ohhh ahhh)
Case #3 two couples, just intervene on ocassion with tidbits and humorous insights. I can do my best rat tat tat with two couples.
Case #4 full house = working hard, no time to chat and do song and dance
Case #5 throw 1 thru 4 out as every day is unique and I have no idea what tomorrow will bring
But overall breakfast
is the time I give to the guests 100%. That is typically when I learn about them, and interact most.
As I say, end of the day at check in time, stepford guests, growl roar grrrr not happy, traveling, tired, hungry, irritable.
Good Day Sunshine...Morning - fresh, clean, a new day - happiness all round!
I want to make them fat and happy in the AM's. Fill them up with good food and conversation and send them on their merry way.
PS - I do not other chores, always need to be available during breakfast to answer questions, check outs, etc etc. So nothing takes me away from them for long. If I am in here while they dine, I have my door open.
