In the door of the refrigerator, condiments occupy fixed positions in a recognizable pattern. Ketchup bottle stands at the front center, mustard to its right, mayonnaise on the left. Hot sauce and relish line up behind them, with vinegar securing the end spot.
Daily use for meals and restocking from groceries continues seamlessly. Bottles lift out and slide back into place, preserving the shelf's steady appearance. The lineup presents itself consistently across openings and closings.
Reaching for mustard brings the hand to hot sauce. Ketchup occupies the former vinegar spot, jams fill the space once held by relish.
The shelf now features a rearranged set of bottles. The prior spots for ketchup front center and mustard alongside stand empty of those items.
The refrigerator door shelf sustains its role with condiments, but the arrangement has become a distinct configuration without signals or markers.
