You will know that I am coming From the jingle of my bell, But exactly who I am is not an easy thing to tell. Children, they adore me for they find me jolly, but I do not see them when the halls are decked with holly. My job often leaves me frozen, I am a man that all should know, But I do not do business in times of sleet or ice or snow. I travel much on business, But no reindeer haul me around, I do all my traveling firmly on the ground. I love the time of Christmas, But that's not my vocational season, And I assure that is because of a sound economic reason.

“Santa Claus”

While Santa Claus is associated with Christmas and is adored by children, he does not travel on the ground, and his presence is firmly linked to the winter season, unlike the ice cream man who operates primarily in warmer months.

“A bellhop”

A bellhop may carry a bell and works in a hotel, but they do not have a seasonal association with children or Christmas, and their job does not involve traveling on the ground as described in the riddle.

“Frosty the Snowman”

Frosty is a character that appears during winter and is associated with snow, which contradicts the riddle's clues about not working in sleet, ice, or snow and not being seen when halls are decked with holly.
