Is this a "secret Santa" type of thing? My former company did that one year - scratch-off lottery tickets were very popular for some reason
People also gave things like candles, a mini foot massager, etc. Price limit was $10 - I'd kill to know where whoever bought the massager got it
My office is medium sized (about 70 people) and we don't do a Secret Santa thing, so I usually get a box of chocolates and put it in the break room with a "Happy Holidays" note. Believe me, they're gone within the hour
